Friend of mine was twenty-three when his parents insisted he buy a home in Sunnyvale since 'he could afford to'. We got to the point of describing the place as an 'albatross' repeatedly, since it cost him many interesting opportunities had he not been nailed into place. He's now very happily in Japan and free of the burden of home ownership.
I'm in my thirties and I've lived in quite a few places. Yet to live somewhere and say 'Yep, this is it. Nothing else to see, this is the best culture has to offer.' and then stay there. Minimalism simply works best to achieve mobility and it's not like you cannot find partners whom also feel the same way.
I find a lot of the hostility and stereotyping over this lifestyle I see here fascinating. Buyers remorse most likely.
I meant the startup world as a fashion or a fad which seems to attract people who are into all sorts of funny ideas. I don't associate startups with productivity, certainly not often useful productivity most of the time.
