Gut reaction, no.

Your competitors are huge and massively respected companies, like Craigslist, eBay and Amazon, which have network effects on their side. Unless you can grow in a niche (ala AirBnB ... but a different niche), and get very lucky, you won't beat them before running out of money. I doubt you will get funding, if degrees are so respected in Belgium.

Unless there's something you're not telling about your plan, it's too likely to fail, leaving you 24 or 25 without a degree.

It seems your main issue is "resentment against the way college teaches". College is like school - it's badly run, and sucks, but the people who say it sucks are just being losers. Just accept the BS, do whatever it takes to pass (including cheating, if it's the norm) and enjoy learning new stuff.
