Privacy features in a currency are a double-edged sword. It means that the money is very difficult or impossible to recover in the event of theft, fraud, or even user errors. It isn't a risk most people want to be exposed to.
However for decentralized people to people transactions, monero may have its chance.
Since I’m far from a crypto bro, I wasn’t suggesting this ;)
I don’t even own any crypto.
As cryptocurrency already requires the safeguarding of a private key or a custodial partner doing so, and generally do not accept rollbacks on the base level, there isn’t that much added drawback to making strong privacy default.
