Owning a house involves paying out of pocket for maintenance whereas when renting, you can have the landlord take care of that for you

Your rent is quite literally paying for the maintenance. You think landlords are just losing money on maintenance out of the good of their own hearts? Of course not, it’s just all bundled up and averaged out into one price with your rent.

owning a house would basically anchor me to one location, which gives me less flexibility as a digital nomad.

Cool, that’s one of many benefits of housing cooperatives. They can act similarly to a landlord in terms of you sharing the cost of repairs with the whole building, which reduces risk, and they don’t have a profit motive, since they’re non-profits, so rent is lower than with a landlord. Some even let your rent buy you equity in your unit, which you can then sell later to get some of your money back if you decide to move, much better than the for-profit landlord that will give you nothing. The only issue is, these cooperatives are repeatedly outbid by corporate landlords, which means there’s far fewer of them than would be ideal.

Additionally, I’ve seen some startups like Cohere that seem like they’ll eventually be able to give you even more flexibility, allowing you to move between units in various locations without having to sell the old one or file annoying paperwork to start a new lease, with at least somewhat cooperative ownership. (although, of course, this is a for profit company, which isn’t as ideal)

I can definitely understand wanting flexibility, but there are ways to get that which don’t involve overpaying to a for-profit landlord. I can understand not caring much about equity, but of course, that’s why non-ownership housing cooperatives exist.

But to actually make those things more widely available, you need to reduce the market power held by for-profit landlords. If they did not exist, these alternatives, primarily the cooperatives, could fill back in the gaps, but provide lower prices, better service, actual equity for those who want it, and still keep the flexibility you get from renting.
