You are right. This is the major reason coinbase is still in the game.
I don't know why but for some reason one of the first wallets/ exchange newbies get to know about or use is coinbase and blockchain.com wallet.
But you can use P2P Transaction of Binance Platform.
U can select which currency you are gonna use for cashout, so basically u trade with someone for selling and buying and binance will be a platform that provide this P2P transaction.
One of example, P2P transaction for cashout your crypto into fiat directly to our bank.
Most people are actually ignorant about this. Binance has lately brought out so many features that enable direct transactions from crypto to fiat and vice versa for most territories.
In fact, where i am from we even have a local binance crypto to fiat exchange platform with very cheap transaction fees.
