Easier solution: You can get YouTube Premium for $2 a month if you just happen to be in Argentinia while you sign up, even if you are using a US credit card to pay.
I’ll just block ads, alphabet is doing fine anyway.
But as the OP says…the problem is that this is not feasible on mobile or TVs.
On my tv… i purposedly picked a tv without any form of smart feature, and have a small nuc to use the aforementioned proxy.
