"Why have 3 roommates in a house when you could have 300 roommates and live in a recently, cheaply converted commercial building designed to be a clone of the Googleplex?"
Co-living is actually pretty great when done properly: it’s not a solution to the housing crisis, and suffers from the same economic problems as WeWork did with office space, but as a resident, it’s great — assuming you want to live with other people.
Most co-living spaces end up going broke (including the one I’ve lived in) so I don’t have much faith in Flow’s viability if it is co-living… but it’d probably be great to live there on VC’s dime (just like WeWork was great when subsidised by VCs).
"Done properly" is probably highly correlated with a high degree of control and ownership (if not in a financial sense, in a sense of ownership and responsibility), both of which are extremely ill-suited to a large company running things nation-wide.
