I mean if you graduate college, get a finance job and live and work in lower manhattan i could see this happening. Might not be a very good idea but its still certainly possible.

There are plenty of 1-bedrooms in high-cost of living areas like NYC, so one way is for the 22-year-old to rent one of them? Now it may not be financially advisable, but if he's making 120k that would be both "a lot less" than 200k and possible to rent a 3k apt, since landlords usually want 40x rent as income.

Step 1: Major in computer science

Step 2: Graduate and get a programming job in SF.

I live in a place close to my work in Boston.

So far I think it’s worth it just in terms of my sanity but it tickles me to see people making more than me complain about rent.
