Persepolis wasn’t in great condition when I went but it also wasn’t a shambles. There’s a gift shop, guards, and a reconstruction of part of the palace, and a lot of tourists. Also a small set of offices for archaeologists. I’m a professional historian so I was a little bummed by the lack of adequate public-facing educational markers and texts, but it certainly can’t be compared to something like the Buddhas of Bamiyan as an excuse for removing items to European museums.
