The reason infinite scroll is bad has nothing to do with the technicalities of the HTML behind it. You could always implement a technical solution for these technical issues but that wouldn't fix the real problem.

It's addictive. There is no "one more page and I'm done" because the page never ends and you're never done. You get to the bottom, more content loads automatically and people say "this looks interesting, let me scroll some more". That's why it's doom scrolling because all you do is scroll, no need for any other input. The bait is always there right in front of you and I'll bet that the algorithm make sure the first couple of posts that load every time you get to the bottom are the "juiciest" ones to make sure you take that bait and keep scrolling.

Pagination hides the juicy bait. It's still there waiting for you but it's hidden until you ask for it. That's a big difference.
