I've just read an article how Russian emigrants around the world (that's up to several million people, more than some European countries) are struggling with opening and maintaining bank accounts, and have to resort to all kinds of workarounds, crypto and Binance included. You might not have any sympathy for them, especially in current circumstances, but they did nothing wrong, and won't cease to exist just because of your lack of sympathy.
Where I live now, there is a growing number of street currency exchange shops which will gladly and openly accept your USDT and hand over cash in either local currency or USD $100 bills; no documents ever asked, of course. That kind of infrastructure did not exist a mere couple years ago.
You might think, why don't just ban it all, but, I'll say it again, the problem with this line of thinking is that if you, as the government, declare large enough numbers of mostly innocent people criminal or "undesirable", they won't magically vanish into thin air overnight; to the contrary, you've just made life harder for your own law enforcement, as real criminals will now have a much larger crowd to blend in.
For many countries where it is difficult to legally buy or transfer USD at international market rates (either because of sanctions or capital controls), there is a thriving USD/USDT/BTC black market, involving, in extreme cases, the majority of population; see Argentina or Venezuela for example. Labeling all of them as "criminals" achieves you nothing.
