of course you can, but the issue is currency control, however, businesses/people in Russia, china, India and any country that has any form of foreign/hard currency control get around this by lots of methods, but the past couple of years, crypto was a popular option, specially p2p crypto, where you send whatever amount of money to the other party in local currency, exchange it for crypto (specially stablecoins), and then sell the crypto for dollars/Euros/swissfrancs and bank it offshore.
so, local money>p2p crypto>stable coins>exchange it for eur/usd>offshore bank account
there are other methods, like local exchanges (not crypto, just regular money exchanges, something like western union but local). in these cases, these exchanges have some sort of relationships with western banks, and all you have to do, is you send them the money in local currency, and they transfer the same amount in usd/euro/whatever from their bank accounts overseas to your offshore bank account.
So, yeah, it's not THAT hard, it just requires you to plan carefully and that's it. if there's a will, there's a way.
