Because they're going to be driven out of exchanges that want to stay in business. That's already happening in Japan and South Korea. I expect it to spread elsewhere. They can lock down on exchanges. They can't do it to coins like that. That's probably enough for now.
Exactly. I actually like Monero (to be fair, don't know or use any other types in the same class) and yes, they serve the specific purpose that only now Bitcoin development is starting to focus on after "solving" the scalability "problem", but if you're happy just using them in their niche markets and don't need a currency that's accepted everywhere, that's fine.
But I still really would like to use Bitcoin, for everything I do.
Japan's effective prohibition on privacy coins (and that's what it is, you can argue it's just exchanges leaving them out to stay compliant but where else are merchants going to liquidate when even bisq Monero volumes are struggling?) could result in others copying, just as they did with Bitcoin. Then you're faced with the same problem.
