the point was the UK is not the only one trying to do it

I don’t see any evidence of the EU trying to do with the GDPR what the UK is trying to do with the CPA.

they can totally enforce the fine by restricting those businesses from doing business within their territory until they comply

That’s sanctioning, not enforcing a fine.

And yes they can do that but that’s not what Ofcom is talking about. Ofcom have explicitly stated that foreign citizens have “duties” under UK law. The word “duty” has a very specific meaning in English law, in fact it’s really one of the most basic concepts. It means there is an obligation on someone and if that obligation is not fulfilled then courts have the power to take action.

Sanctioning a foreign citizen doesn’t imply an obligation. There can’t be an obligation because a foreign citizen, by definition, is not subject to English law. Ofcom is claiming that foreign citizens are subject to English law.

I don’t know how you could get it more wrong.
