This is what happens when people want to "do a startup" more than they want to build a business doing X. The passion for the idea/product should come first, with incubators (if deemed necessary) being used as a tool towards achieving that goal.
I get wanting to start a company around your idea. In that case, the company isn't the goal but rather the medium for pursuing the goal, which is to push your idea/product. I don't understand wanting to start a company for the sake of having a company.
