Thank you. No, I don't think you missed anything. Happy New Year, by the way. :)
Personally, I think "objectification" is something everyone does to a greater or lesser extent (if they're honest), and it simply doesn't bother me. And yes, I'm an equal opportunities "objectifier" (is that a word?). Women can (and do) objectify men, and it doesn't bother me at all.
In the case of Anora, I think it would be a bit disingenuous not to show her stripping, given her profession and its relevancy to the story (a story shown through her eyes, unlike The Florida Project, where it is through the eyes of a child). So the opening credits in particular are a good way of doing this, whilst filming it in such a way that (to my mind) provided some insight into the assertiveness of her character. It is there for titillation, yes, but not purely for titillation. She then goes on to be revealed as a fascinating character. Or I thought so, at any rate.
The issue about destigmatising the world's oldest profession is another matter entirely. Personally, I'm quite conservative in my real-world views as far as that's concerned. I'm inclined to say that poverty and social inequality are at the heart of the matter, not "empowerment" as some feminists have stated. That said, I do not believe women selling themselves should be criminalised for it at all, to be clear. But regardless of Baker's stated intent, I think the film encourages us to view the characters in a non-judgemental way.
