When I think about it, yeah that's probably one of the many reasons why I don't promote not just USDT but stable coins in general. There's no real benefit if you would just convert your fiat to USDT and move funds because you can simply do that with fiat. For international transfers, USDT could be faster and (might be) cheaper option than sending fiat since there's no bank interference but it still doesn't fall under decentralized currency as others have said.
