Believe it or not, people exist who don't want to own a home and would rather rent. There are also plenty of times where it is a better idea to rent than buy a home- plenty of people who bought right before a housing market crash then needed to move for a job can attest to that.
Generally, if you aren't sure that you're going to stay in a home for several years, you're not getting any equity back out if you need to sell... Especially if you had to do any big repairs or maintenance.
Landlords are a necessary part of a functioning society.
imagine you lived in a world where roads were all private and it was just how things are done that you pay fees to use them, fees set by the roadlords to keep them confortable. you'd say roadlords are a necessary part of a functioning society, but you'd be wrong, wouldn't you? you'd be confusing how things are with how they must stay.
It's an interesting point. There are private roads, and most that I've used have been on par with public roads of equivalent traffic patterns (mostly because people who put in private roads are the same ones hired by the government to put in public ones).
What's more interesting is if you take that extreme and flip it back to housing.
Imagine a world where:
You are banned from owning land or housing. There's a variety of options to live in, but limited by what the government decides is fitting. Then, a popular movement within government decides that a particular type of housing is not appropriate for society, and starts destroying all of those houses. Instead, they decree, the best and only type of housing that should be available are communes where everyone gets a bed but zero privacy. You're not allowed your own four walls, you have to share space with everyone.
It's so much more efficient! they decree.
Well, that's exactly what is starting to happen to roads in some major cities. Parking spaces are being removed in favor of expanding public transportation. Entire blocks are being declared off-limits to private cars to make them "walkable".
I'm not really advocating one way or the other here- my point is that it's kindof silly to compare roads and housing at such extremes, because the benefits and consequences of various polices are not directly analogous to each other.
