According to whom exactly? For me, permanent means "permanently without breaks".

If you want another word for that, go with "Continuous".
The ISS has been continuously occupied since November 2, 2000. But it was not, in fact, expected by anyone to be a permanent station; It is made of non-replaceable parts that age and fail (decade scale), it only has very limited life support supplies on board (month scale).
I would call the ISS a permanent station.

Every part of the ISS is replaceable if you want to.

I still don't see why self-sustainability is a part of being "permanent".
