Bio contamination is my guess. Even the ISS is getting quite a few gross spots that are becoming mini ecosystems. Of course the experiments are on purpose, but there is a lot of astronaut filth and other basic growth. Much like how an old house cannot be kept up to date by making additions and rennovations for ever, the ISS cannot go on for ever. At least not without something akin to a serious rennovation, but at that point…

FYI, houses do not work that way. They can, in fact, last forever as long as you keep up with the maintenance. The main reason they don’t is that people either abandon them or want to build something else in their place (i.e. they become functionally obsolete).
Now, if you want to argue that the ISS is functionally obsolete, I could see your point… but then again, it’s hard to argue that a thing is obsolete when nothing exists to replace it. Even if the engineers aren’t thrilled about trying to interface new modules with the decades-old stuff, I don’t think that’s a good enough excuse to throw away the entire existing thing and start over from scratch.
Well, houses can be stripped down to a state where they can’t support their primary function while they are renovated. Space stations are harder to handle in that way.
Okay, but if we’re intending to have a permanent presence in space, it’s unreasonable in the long run to have to keep throwing stations out completely and launching new ones from scratch every few decades. We’re going to have to figure out how to do “space renovations” sooner or later. Why not try now?
The easiest way to do that in the long term will likely be to have several space stations in orbit at a time so you can renovate one while using the others for habitation for the people who do that work.
Depends. Not even many stone buildings last many centuries. Wooden structures tend to be much less, and humanity has seen many stone structures slowly turn uninhabitable.
Besides, in space, there is much, MUCH more space. There is only a little need to fight over orbital space, let alone literal adjacent space. We don’t need to rennovate the ISS to reclaim ideal space.
Whether or not you know about them, there are also several plans ongoing for replacing the ISS, too, so your inability to grasp this is… kinda’ weird.

What? Room inside a space station is incredibly expensive because we have to design, build and launch it!

Key word: “plans.” I.e., things that aren’t actually built yet and in fact might not ever get built.
Throwing out the ISS before we have at least part of a replacement in orbit is an excellent way to risk failing to have a space station completely.

I agree. We are not doing that though. Haven-1 is scheduled to launch NET 2025, the Axiom orbital segment is NET 2026, Orbital Reef is targeting 2027, and Starlab is targeting 2028. Even if these schedules slip a couple years, they would still be ready in time for the ISS deorbit in (or after) 2030.
