Excellent point. The initial intent of my squabble wasn’t trying to deny that counter-examples exist, just that when comparing 100 houses to 100 apartments, that there seemed to be losses in living space for the apartment (law of averages and whatnot).

I had made another comment on that /c/FuckCars thread that calculated that if all of the homes had 1-car garages (which is not uncommon for a lot of dense low-density suburbs), then the homes would be 1740 SqFt with the garage / 1500 SqFt Livable, and the apartments would be 1009 SqFt livable. So a 33% loss of livable space in the image with what I would consider a reasonable assumption.
