What stops them from submitting PRs from another account?
I can't speak for all, but many mature open source communities have explicit or ad-hoc reputation schemes that are used to triage contributions. A fresh account means starting over with zero reputation, which in turn means your contributions wait at the back of the line.
What part of [0] or [1] makes you think that it is easy to have multiple accounts?

Well. This is Debian, known for how strict they are about vetting developers. I just remembered Sladen refusing to key sign because my passport circa 2005 didn't have a machine readable slug in it.
Debian is notoriously very strict on accepting maintainers and they are not anonymous.
Reputation, or lack thereof.
Proof of authority, essentially.
In anonymous systems, where we don't use real names, your "handle" has an "age". That becomes your most prized possession.
I have a reddit account thats over 12 years old. I have left the posts/comments open. That means, my "post history" becomes a way to advertise my skills. I can reference comments from a year ago or 6 months ago about a certain topic to show how I handled something. That does have an effect on people.
As opposed to a random 1 day old account. No one takes them seriously, I guess the same is here as well

Nothing. And that's the problem -- the issue isn't "should a contributor be able to use AI" it's quickly becoming "is this entire contributor an AI agent". Every actual-human who gets a bad first experience hurts the project. The contributors having to be suspicious of new people hurts the project. The whole thing just sucks, and I don't know how to fix it.
I use claude-code, but the AI ecosystem and some of the autonomous tooling coming out of it -- which some people "helpfully" use irresponsibly and point at OSS projects they aren't personally invested in -- enables a LARGE amount of abusive behavior towards open source projects. This is even before we get into how many infrastructural resources crawlers eat up.
Me, and most other OSS contributors, signed up to be a mentor, to create software, to work together ... not to be the equivalent of a reddit moderator banning AI agents left and right.
