On the contrary, pagination makes it impossible to keep your place in the list if it changes between page loads.
The challenge is to retain an ordering over the result set. How would infinite scroll behave any differently in this case? The changing results seems to be an orthogonal concern to pagination/infinite scroll.
Ah yes, let me just look at Instagram for the ideal model of infinite scroll UX. You can't even scroll up to something you've actually subscribed to that you didn't mean to scroll past without it tossing it into the memory hole and replacing it with something you don't care about.
Did you think HN has an unusable and bad interface? It seems to be a remarkably popular website despite having hard pages that change order on every refresh.

Well, that's obviously false. There are two styles of pagination:
https://yourblog.zox/archives?page=4
https://yourblog.zox/archives?before=2019-06-03&count=10
That second style will never change (unless you insert entries into the past). The first style will change. But it hardly makes it impossible to keep your place in the list; if you come back three years later, you'll find that that link goes to a random location, but if you come back next week, that link is going to go to a place that is very close to the place you left off, requiring minimal adjustment to find your place again.
How are you going to keep your place if the order changes anyway? What is your place if the order has changed?
If the order changes, all bets are off regardless of pagination or infinite scroll.
