I dont really see a problem. Those people will just have to open up a bank account and if they unable they can always get a prepaid card that allows direct deposit.

Many people want to keep it in US currency, and if Google does not support sending $US to $US account outside of US, they don't like it as it works against their business.
People/companies already spend $US directly to create revenue, and they don't need those funds converted at all.
Plus, it is not just AdSense but all else Google, like GAN for example (again, being active in US by spending $US).
Conversion rates are awful when using such payment methods.

BTW, when GAN was Performics, I was able to receive $US payment directly to my $US account outside of US.
