You don't seem to have countered any aspect of my argument, so I'll rephrase it for enhanced clarity.
Current laws about minimum sizes (WRT size alone) already sufficiently allow small sizes (as far as interior size of the unit is concerned).
Commonly it is __other_laws__ such as access to two fire escapes which cause larger sizes than some might desire. An example addressed in my reply's following lines 'Fireproof Buildings' which some localities allow to relax such rules.
