In capitalism, the proper way to do things is,
1. create good or service people want
2. sell it to them
in that order. Kickstarter reverses the natural order of things, and thus is bound to lead to all sorts of perversions.
Just take the time to make a proper product and self-publish or whatever, then you can't be cancelled by anyone. You also can't collect a wad of cash and then delay for years and eventually give people nothing. It's better for everyone.
Cancel Kickstarter!
The "natural order" sounds like a conservative version of the "right side of history", which is a toxic faux-argument. But the more general point is an interesting one, because from a neoclassical perspective (often represented by the Austrian school, today), the entrepreneur what makes the economy more efficient, and thus is essential to economic growth and development. The entrepreneur does this by taking risks, specifically expending capital and resources today in order to make the production of consumer goods more efficient tomorrow. The market rewards those who act efficiently, and destroys those who do not, and the end result is a more efficient process of production. That's why entrepreneurs reap the profits, and not their employees, who are paid before the capital development is finished, and thus don't take the same risk.
But while entrepreneurs sometimes use their own money, they more commonly get it from investors. So getting money before something is produced is not significant change, for the creator of a Kickstarter project. The main difference is they have many small investors, instead of a few large ones.
But it's a major change, from the perspective of the investor, or backer. Because the backer has been stripped of the potential upside of being an investor, which is the profits. At most, they get what they preordred. So they're investors from the perspective of the KS creator, but from their own perspective, they're not investors at all. They're consumers who pre-ordered a specific product. This creates an asymmetry of expectations, because the creator sees them as investors who took a gamble, but the backers see themselves as people who just paid money for a product.
