I don't like old school gaming that much, but I recognize that others do. You can dislike what I like, but don't imply that I'm wrong or a moron for having different taste. The OSR is full of that attitude.
And vice versa by many others (not including you). The same range of personality types are found within the OSR as there without.
If you want the easy going OSRites then the OD&D Discussion Forum is where a lot of them hang out.

As for Kask's post, a lot of what he talks about happened in my hometown in rural NW Pennsylvania. I wouldn't say that it fell by the wayside because of greed. Basically it changed to a single character focus largely because campaign hopping died out (both with characters and players). With that, the referee will fast forward the healing process, update the game date and pick it up from there as there only a single group that played constantly.
Note this is what I experienced in my hometown back in the late 70s and early 80s.
And what Kask doesn't mention or didn't experience was the crazy issues experienced by people hopping from campaign to campaign. One DM would handle out magic items like crazy and so on.
Of course when it starting everybody want to play as much as possible and were willing to put with a lot in order to play. At least among us junior high and senior high gamers. Finally within a handful of years, still in high school, various groups solidified and campaigns became largely about a core group starting out and seeing it through the end game of high level.
Some made the end game about becoming a god or gaining god-like powers, others (like myself) went the "build a castle establish a barony" route.
What I was personally noted for back then was allowing people to make substantial changes to my setting and then using that as part of the background for the next campaign. A lot of referees back then got really bent out of shape if you "trashed" their campaign world.
The stuff I create today and write about is a consequence of my learning to keep with my players tampering with my setting and to keep subsequent campaigns interesting.
