As far as webdev goes, you could do a bootcamp and be earning money within 6 months to a year. That's money that's hopefully going into your pension fund and earning interest while your peers are still in class.
Or you could learn to code using cheap and/or free resources. College isn't the only place to learn things nowadays and I think a lot of people haven't caught up with that yet.
I used to think nothing could beat the college experience for bonding but I think the formula of lots of people doing the same thing every day in a niche environment they want to be in is easily repeatable. I'm still in contact with digital nomads I hung out with in Bansko two years ago and I was only there for a month. But it was an intense month of seeing each other every day, just like college.
Oh and don't worry about not finding a dev job if you don't go to college. Employers are coming around slowly and there are lots of success stories out there: www.nocsdegree.com
