You're not wrong, but what you're missing is that the post you're replying to is a part of the process of contributors feeling out what exactly is Kickstarter. If founders are going to treat it as a source of seed money for which they have to give up no equity, then contributors will re-adjust their expectations and treat it as such. And giving seed money for no equity is a bad bargain, and it won't take long for contributors to realize that.
