Separating different things to figure out their role in an overall system is a completely normal and useful thing to do. [...]

that isn't my point. my point is that rent has always existed within unjust systems, and is itself a tool for those systems to accumulate wealth. if we're taking gears out of a meatgrinder and trying to identify just how much that gear contributes to the problem of grinding people into meat, we're missing the point. in practice, the system in which rent operates is built to deprive people of resources. but even then your framing is not agreeable to me. we aren't talking about a machine, we're talking about a complex socio-cultural phenomenon that developed organically over generational time spans. the idea that we could even rip the word "rent" out of the context it exists in and get anything worthwhile out of analyzing it like that is not reasonable to me. like, cultures and economies don't have parts like an engine do, they have trends and policies and outcomes, and those things can't reasonably be reduced to cogs in a machine.

That’s not an argument against rent, that’s an argument against students having different means and having to pay for things in general. Why do students have to pay for food themselves? Why do they have to do their own house work when others can afford to hire someone? Those are all good questions, but they only concern rent in so far as it’s also a thing people pay money for.

you're doing the thing again. separating rent out from the system its built into and analyzing it only as the act of exchanging currency for housing itself. i'm trying to engage in a systemic critique, not a stubbornly isolated look at a single piece of a larger whole. the problem of students "having different means" is not the point. you have to look at the larger picture. on a population scale, how does the requirement to pay your resources into the pockets of wealthier people for basic housing affect a society?

rent is, in the case of the university student, a material obstacle towards getting an education. those who do not have money or home ownership are more likely to be denied an education as a result, and will have less access to money making opportunities in the future. the money they could have been saving for themselves goes into the pockets of richer (whiter) people, so they are less likely to be able to pass on money they make during their lifetime onto their kids. non-white people are much more likely to be renting than white people, and that is historically because non-white people were restricted from home ownership in the past, and were not able to build the kind of generational wealth that comes from home ownership. rental arrangements reinforce existing social stratifications by providing the means by which the wealthy (and white) can continue to extract resources from the poor (and brown), as they have done for generations past.

like... sharecropping was rent, and its sole purpose was to explicitly ensure that freed slaves continued to provide wealth to their former masters. the actual observable impacts of rent are to transfer wealth from people who have no resources to those with resources to spare.

[...] If there are more houses than people wanting to live in them then houses are essentially “unlimited”, in the sense that you’d probably need to pay someone to take it off your hands. [...]

i was being facetious. my point was more that these factors you seem to think are separable are interlinked. just as a wake up call, there are currently more houses than people wanting to live in them. there are many multiples of houses left unoccupied for each homeless person in the United States, and the price of housing hasn't done the thing you're saying it would. instead, homelessness is increasing as landlords continue to raise rent, and the prospect of owning a home is becoming more and more out of reach for more and more people.

Rent doesn’t require private ownership. Property can be owned and rented out by public entities, and that’s actually pretty common.

there is a rabbit hole i could go down about this, but i don't really wanna. my position is relatively simple. housing is a human right. putting literally any barriers up that prevent people from getting a place to stay are wrong. imposing extra financial burdens onto the people who have the least money is wrong. rent is such a burden, even for public housing. nobody outside the people who live on the land should have ownership over the land, not wealthy folks, not the state. housing co-ops, self-governance, that is what we should strive for.

As an example, burglars require air to live, but the problem of burglaries cannot simply be reduced to the existence of air.

i don't really know how to respond to this. air isn't a socioeconomic phenomenon with a proven history of driving wealth inequality? it doesn't interact with race and class in ways that structurally disadvantage people who are poor and brown?

And uhm … the universe is infinite as far as we know, but that’s another discussion entirely.

lol. disagree, but fine, ill be less hyperbolic. "the parts of the universe we can build houses on currently are finite." is that better?

That might be what you’re calling personal ownership, while I’d just say that’s private ownership within healthy limits.

i'm just gonna end with this: i'm not prepared to expand upon the exact shape of why i think you're wrong, and why i think your rebuttals fail to provide a compelling challenge to the ideas i'm trying to convey. (that is not to say there aren't compelling challenges to socialist ideas, there certainly are.) i used to hold a very similar position. the idea of doing away with private property once seemed ludicrous to me. then i actually engaged with socialist and anarchist arguments for why they believe the things they believe, and i found them compelling. i'm not saying you will too, but i am saying that the reasons i believe these things are knowable and there's plenty of media out there that explains it better than i ever could.
