Enterprise companies are built in a way that slows the process of getting shit done to an absolute crawl (red tape, politics, approvals, process and god-knows-what other nonsense that somebody in a position of authority has decided they're going to throw at you that afternoon), and that kind of environment is simply noxious to the kind of person that has the audacity to think they can start from nothing and build a company that employs hundred(s) and pulls in millions in just a few years.

It really is that simple. You can even find some small companies that entrepreneurs wouldn't last a second in, because they have this same mindset.

The point at any company where getting things done becomes less important than making sure people (and by induction, the company) follow orders or don't screw up, is the point at which entrepreneurial minded folks can no longer thrive at said company.
