Bad strawman, worse reasoning. Obviously if the benefits of the regulation outweigh the cost then it's worth it.

In this case the vast majority of the benefit accrues to non-germans (because the German population is small and few Germans profit from copyrighted music) but the loss will accrue only to Germans (since they can't use Suno).

That's the same with India banning scam call centers. Most of the benefits of that policy would accrue to Americans.

Yes, and you'll notice india has been pretty lackadaisical in cracking down on scam call centers.
