Well yes, hence my last sentence - there will always be some people who have to rent (or just prefer it), and for those people, we could have public housing. Basically housing that's treated as a public infrastructure - run not for profit, but for public good. It's really not that hard to grasp - remove the landlords from the equation, and set the rent prices to exactly the cost of maintaining the properties.

If you remove the landlords leeching away extra value for investment profit, and instead just charged what it cost to make the housing available, it'd be cheaper by definition. Providing essential services at an affordable cost is literally the whole point of civil infrastructure

You don't need landlords to give people a place to rent, in the same way I don't need to pay someone to bring water to my house, or haul my sewage away, I use the public utilities in my area. And I'm not even talking about subsidizing the cost with tax dollars (though I think that's a good idea), you could give renters significant savings simply by not trying to make money off them
