I agree that it's not fair to say Coinbase is as bad as Binance. Still, it engaged and supported pump and dump schemes and wash trading , so I don't have much sympathy.
Bitcoin's price will be hurt if fiat on ramps are removed, no question. In the long run, bitcoin will be better off. I'm lazy, and don't relish having to deal with p2p buys either, but we have to take our medicine.
