The fact this isn't talked about much even more so after Canada froze bank accounts watching people tx bitcoin and ETH addresses tied to other ETH addresses are being black listed / banned is really bad..
BTC will fail or much much much worse become the money of enslavement if privacy is not added.. Unbreakable privacy..
Privacy and anonymity are important. Whether bitcoin will fail without them, I don't know. At some point bitcoin reaches a point where one doesn't need to be exchanged for fiat, people just exchange in bitcoin which makes anonymity even more important. But also easier since you don't need a centralized exchange.
