I'm sorry, I'm not quite following what you mean by "a trade of 40 hrs for 10hrs".
Working remote, for example, you could hang out with friends or family or neighbors in the middle of the day for lunch, the commute savings time is just a bonus.
In theory you could, but I don't think remote work necessarily enables substantially more in terms of mid day relationship building, at least not if you're actually doing anything substantial during the working day and don't want to sacrifice your evening time by working into it.
