This is a very American way of looking at things. In many countries singles live with their parents and families live in apartments and the country is not so vast and big so your social circle can go with you all the way from school just because they still live around. So the level of isolation and space can vary and not necessary depends on the parameters you have mentioned, however in the individual level it is pretty correct, the level of isolation and convenience will dictate how happy a remote worker is. Personally I have found that a mix of 2 days at the office and 3 at home works the best for me.
