You don't need tiny apartments to have density. You can do it with smaller single-family houses on smaller lots, narrow one-way streets, and alleyways for parking instead of driveways and garages. This is how the pre-war streetcar suburb of Riverdale, Toronto is designed [1] and it has much higher density than the rest of the city.

Sure, it starts with "just do row houses" and "missing middle" and in two generations it becomes "we should allow SROs".

That's a propaganda channel that "conveniently" ignores everything against their narrative.
These kinds of density still require cars. Unless you want to have a stay-at-home spouse who can do full-time housekeeper duty (like in that Toronto neighborhood).
