As a young person, I can afford to live alone. I'm definitely privileged in this regard (and don't live in NYC or SF) though.
Even living with one roommate I felt the isolation, since my office was still my bedroom. Placing my work desk in my bedroom was probably one of the worst moves I've made for my mental health; if my apartment had space to make a shared office I may have had a difference experience and therefore a different opinion.
I think a 15 minute walk to a low-commitment workspace was a good fit for me, but obviously I can't speak for everyone.
lol young people in 2023 can't afford to live alone.
even entry level FAANG salaries in NYC or SF mean you're still living with a roommate if you're anywhere near your work campus.
