This is probably too much of a false-information echo chamber to penetrate anyone's consciousness, but most of the points being made about the low fatality rates of Covid-19 have been clearly and repeatedly debunked as results of false positive rates on tests, fatality or serum positive test rates from studies that were too small to yield meaningful results, over estimates of asymptomatic cases because people were not followed long enough to see them get sick. Add in a healthy dose of lies and assumptions.
The reality is that the case fatality rate (based on confirmed tests) averages close to 2 % (varying between about 1 and 5 %) at all times and places where it has been well documented in a big and well tested population. This is true in all of the heavily tested countries with basically modern health care systems in the US, Europe, east Asia, South America, etc. Obviously the true case fatality rate is lower than this because it doesn't account for people who never receive a test. But for much of the well documented period testing has been widespread, positivity rates very low, and antibody assays on big populations consistently fail to support the narrative that big chunks of the population have already had the disease without getting diagnosed. The real multiple of people who have had the disease is something like a factor of a few.
The relationship of case fatality rate to age is widely recognized, but is not nearly as dramatic as people usually like to quote in their anti-mask tirades. Yes, 90 year olds have enormously greater true case fatality rate than 10 year olds. But most of the adult population has significant risk of death. If you are 50 or so, your case fatality rate is closely similar to the overall population average (so, of order 1 %).
The rates of signifiant morbidity (really long lasting impairment) are something like 10x or more case fatality rates.
Add this all up, and it is obvious why the economy is not going to just spring back into mid 2019 form when the world overlords from the UN stop oppressing the sheeple (or however you like to present absurd conspiracy theories). People don't think a ~ 2 % chance of death and ~20 % chance of serious long term health problems is worth flying to some stupid business conference where nothing much will happen anyway. Most of the restrictions on movement , vacations, eating at restaurants, etc. are a mix of semi-enforced rules and a lot of voluntary restrictions. If you want to get everyone back in their seats at Denny's or wandering around Disney World again, you need to reduce the risks down to the levels most people find acceptable. Like has been done in Korea, New Zealand, Australia, and a number of other places.
That's a mix of misleading and false information. You base a lot of your conclusions on the case fatality rate (CFR), which is defined as the number of deaths over the number of positive tests. That's not a very useful number because it is highly dependent on the number of tests performed, their sensitivity, and who is being tested. If those factors are stable (within a fairly uniform region where the other variables don't change very much), the CFR can be used as indicator for whether the disease is trending up or down. But comparing CFRs across regions or when the number of tests or other factors are changing is pretty useless, and it says little about how dangerous the disease really is it. The reason the CFR was cited at lot at the start of the pandemic is because it's easily calculated, not because it's a good number.
The infection fatality rate (IFR), which is the ratio of the number of deaths over to the total number of people infected, is a far better number. But, obviously, this isn't as easy to measure as the CFR. The IFR requires representative population-wide studies, looking for the existence of antibodies. But we have that information now, for nearly all developed countries, and samples from the rest of the world.
The IFR varies, but in developed countries where the healthcare system hasn't been overwhelmed, it tends to be about 0.3%. That number may actually be inflated by a factor of two, because there are indications that the tests miss about half the infections (half the people who reports anosmia, the most characteristic symptom of the novel coronavirus, don't test positive for the antibodies). Countries with younger populations have much lower IFRs, like India (0.1%) and Africa (Kenya and Malawi 0.01%). The only places where the IFR even approached 1% is where there was a collapse of healthcare care, specifically elderly care (e.g. Spain).

https://www.medrxiv.org/content/10.1101/2020.08.06.20169722v2Your attempt to underplay the increased risk due to age is also incorrect. One of the disease's most remarkable aspects is how closely COVID-19's mortality profile matches the natural mortality profile. In other words, your risk of dying with SARS2 is almost perfectly proportional to your risk of dying without SARS2, which means it increases steeply with age.
In Europe, more than 90% of deaths were 70 years or older. The median age of death in all first world countries with a developed health system is between 82 (Australia, Austria, England, Germany, Italy, Spain) and 86 (Canada, Switzerland) years of age. The exception is the USA, with a median of 78 years.
Even in Italy, where the IFR for those who were 80+ was 30% in the first phase (systems overwhelmed), and 8% in the second phase, the IFR for people 50 years and younger is less than 0.01%. In Spain, the IFR was less 0.03% for people age 40 or younger. In NYC, it was 0.12% for those 25 to 44, and 0.01% for those under 25. In England, 0.03% for those under 44 years. And those are all worst-case scenarios, where the systems were overwhelmed with patients.

About 10% of people who develop severe symptoms do develop persistent symptoms, which last for several weeks or months. This is still developing, but it's been oversensationalized in the media, which has reported things like permanently reduced lung function in a high percentage of young patients, but all indications are this is just covid-induced pneumonia, and thus relatively short term. The bigger concern is the effect on the heart. COVID-19 is primarily a cardiovascular disease, and there are reports of mild myocarditis. But again, this was initially oversensationalized, and now its incidence rate is considered to be comparable to influenza.
