since some people are not in a position to buy land and need to borrow it.

Some people have no desire to buy land, and want to borrow it. More than half the people I know (and I'm in my 40s now) have no desire to hold the liability of needing to sell a property to be able to move halfway across the country or world. They don't "own" their, so they see having to literally own it as a problem. And they are willing to pay more in rent than a mortgage (which happens regularly in some areas around me).

There are shit landlords, and there are decent landlords. I think half the problem is that while some areas have great protection for poor renters, they often don't have great holistic renter protections. In my state, for example, government-subsidized rentals have the most apartment quality regulations. But after that, you're expected to leverage your rent to force action... without actually withholding it in any way somehow. And small business rentals? Even worse. I have a buddy who runs a breakfast joint. The heating system in the building died, so the landlord said "well if you want to stay open in the winter you should fix that". So he installed a minisplit and the other business in the building had to close for the winter. Ultimately, both businesses started withholding rent (against lawyer's advice) and he finally caved and called his renters "cheap bastards" as he got heating installed (and it was like a comedy that the heating company walked out on him twice for his after-contract renegotiations).

I'm ok with someone owning and renting out a building. But it should be somewhere near the level of quality the renter would maintain the place if they owned it.
