Ah, you've never worked somewhere where people regularly rebase and force-push to master. Lucky :)
I have no issue with rebasing on a local branch that no other repository knows about yet. I think that's great. As soon as the code leaves local though, things proceed at least to "exercise caution." If the branch is actively shared (like master, or a release branch if that's a thing, or a branch where people are collaborating), IMO rebasing is more of a footgun than it's worth.
You can mitigate that with good processes and well-informed engineers, but that's kinda true of all sorts of dubious ideas.
