I think the MBA in the post is just a story of "How I got into debt after some entrepreneurial education". It could have been "After my first 4 startups failed to go huge and I was in debt up to my eyeballs I decided to start another".

Yes, totally (that was my point). Not dissing the MBA -- it was also an amazing experience and investment / risk. My real point was about weighing the financial considerations of taking the startup plunge against the intangible benefits. There are many forms of "debt", from forgone salary, stress on one's marriage, sacrifices to personal health stemming from high sodium intake from top ramen, etc.

Good point, I've just seen a lot of 'screw business school, spend your money on a startup instead' type posts recently, which certainly wasn't the case in this post.
