A theoretical way to circumvent Android developer verification

While it is technically feasible, it is not a good idea to try and find a technical solution to a people/organisation problem.

Do not accept the premise of assholes.

I hope we can get the EU to fund a truly open Android Fork. Maybe under some organisation similar to NL Labs.

Furthermore, the need for a trustworthy binary to be auditable to a certain hash or something would make banning this a simple task if Google would want to go that route.

How are things in the EU on whether it's legal to buy a SIM card without showing ID?

It is neither illegal nor hard to obtain such a prepaid SIM card.

That very much depends on the country, many require ID.

You can use any country's SIM card in any other country, regardless of its registration status.

… if you have roaming coverage.

And even in that case, doing this for a long period of time violates most roaming policies

There's eu(maybe even EEA?) wide free roaming legally mandated since I think 2017 or so? But it's not a permanent solution, your second paragraph still holds true.
