It depends what you are trying to do - if you want to build stuff and create businesses, it's probably better to spend those two years doing just that. My B School was totally paid for through scholarships, but it still meant that I didn't make any money for two years. I would have been better off not making money for those two years, getting a cheap apartment and building stuff.

That said, things I am glad I have from the B School experience: 1) A network and some great friends I wouldn't have otherwise met; 2) Efficiency of thinking - I can get to answers very quickly; 3) Job opportunities - but, again, if that's not what you are looking for (wasn't what I was), then this isn't much of an advantage.

On balance, I would say it's better to just go build than go to B School, but that's probably too general off a response.

Happy to answer more.
