No, the ISS never was permanent. It had a limited lifespan from the outset. It's actually beyond the original 15-year life. But it is not indefinite.

That's true, in the sense that "A word means whatever I choose it to mean". If you were in a flat in an apartment building scheduled for demolition in 2030, would you call that "permanent housing" ?

I think it depends on the context, but for a home, I would still call it permanent housing if it’s supposed to be demolished in 2070, but probably not by 2030.

I’m not sure the bases in Antarctica all have a set lifetime so it doesn’t really matter for the original point.
