I can think of a myriad of other reasons than sheer cost why I might not want to buy a home straight away
Me too and you make a great point. The problem isn’t with renting homes as a concept, it’s with renting from a private owner at market prices. Publicly owned housing for rent at maintenance cost-prices would eliminate the exploitative relationship and still allow people to rent for as long as they want.
I’m genuinely happy for you getting a good landlord, but access to housing shouldn’t be conditioned by being lucky to get a decent and altruistic landlord (a minority in people’s experience, hence the massive upvotes of the post).
