Captain obvious over here.

If the dollar is no longer a unit of account, then "pricing" Bitcoin in USD won't happen on exchanges either.

However, it does not follow that there won't be UTXO bands in a non dollarized world.

But it's all silly in the medium run because dollar dominance is going to INCREASE, not decrease) in the next several decades. All the small currencies are going to get absorbed into a global fiat oligopoly of 2-3 fiats. The bands are doing to strengthen over that time, not weaken.

Then, even in the case of hyperbitcoinization, society will probably convergev on best practices that will cause banding.
