living alone is inefficient for so many reasons.
it should be rare - and i expect it has been in the past.

i mean its an expensive luxury for those who like it and can afford it , should not be seen as a norm, status quo, or something that most people “lack”.

i’m not saying rent isnt too high a fraction of living costs, and i am in favour of seriously considering rent controls in ome city central business districts.

But I dont see a benefit in setting or condoning unrealistic expectatioins.

Put another way, if a city implemrnted rent controls aiming to improve affordability, but ended up with declining household size and lower population density in cities, then that’d be a bad outcome.
