I also see a lot better community with less people, and I'm sure there are many reasons for that.
Which isn't to say anybody should be forced into a multi-unit building and mixed-use neighborhoods. But as you point out, prices for these types of settings are often higher than detached homes, indicating that they are under supplied and more people want them then are currently allowed to live in them.
I guess I’m just saying there should be cheap smaller houses and condos in cities too, not just rental places.
(One of my more heretical opinions is that homes and land shouldn't be considered investments, and should perhaps not be a method of wealth building, as it turns every person into an investor whether they want to be or not. Which fuels regular people to take control of the local political processes that block new homes with talk of "luxury condos" and "stack and pack." If we are going to do something like this I'd favor a sovereign wealth REIT that redistributes the wealth more evenly and removed the financial incentive to be anti-competitive in land use decisions. That, or tax away all profits from speculation on land gains.)
Apartments create greater affordability, they allow for designing cities with lower carbon impact than single-unit homes, they allow better community, more connections, cradle-to-grave living, they allow people to survive without having to get in a car to do any task during the day. They are fantastic. I would live in a "stack and pack" home in an instant if they were allowed in my community.
