The point of "downsizing", related to "downshifting", is to remove the excess largess western cultures have grown accustomed to. To some anyway. It is also a voluntary choice so no need to worry about concentration apartment buildings where flats only have room for one TV set.
I live, with one other person and three cats, comfortably in 54m2 (581 sq.ft.). We used to live slightly less comfortably in 42m2. I know four or five couples who live in 30-37m2 currently (which I, you will note, said was "livable"). And others that have 90m2+.
90m2 may well be standard for two people where you are at least but it is wasteful in terms of resources if nothing else.
