That would be a great outcome.

But I wonder how much someone from an unbanked community cares about privacy.

I can see that happen though with stablecoin ecash. I guess that'll be a obvious usecase. Have your own little USD mint and be protected from your own fiat being devaluated against the dollar.

Of course, I'm all for native bitcoin. But here we're talking about ecash, so i guess that would be acceptable.
