It's fine to feel that way, and anyone else who does can sit back and wait for the final product before buying the game, but don't forget that without the early backers who were willing to put up hundreds (and some even thousands) of dollars there wouldn't even be a Star Citizen game.
I'm not at all convinced of the economic truth of this statement. We've had this discussion on the board before. The capital has to come from somewhere. If there are enough individual players out there willing to contribute then that would seem to imply there is enough of a market to interest investors.
But investors are a lot different from contributing enthusiasts. They usually want inconvenient stuff like equity, a shareholder agreement, a seat on the board, and yeah they often use that stuff to put pressure on management to deliver. Not sure that is a bad thing, frankly. But in any case they are investors, and they know the risk they are taking.
Kickstarter contributors get no equity, and have no influence over anything. All they can do is pay and wait. Dream investors, imo.
