Well, 99%+ of my transactions are in USD

When abroad, prices are listed in the local currency, and I have to do some mental math, but yes the transaction does currency conversion automatically, with a fee that is typically higher than I would have realized if I swapped beforehand.

The point is, what currency will prices be listed in and do I have to jump through these mental hoops everywhere I buy things? Unlikely that most consumers will want this situation and extra layer. If it's listed in USD, why not just pay in USD and avoid the conversion stuff all together?

That is why a plethora of currencies will not pan out. It's not a out technology, it's about people's minds and behaviors.

Well worst case nothing changes and the prices are still listed in the same currencies they are today. But if crypto is even a little bit successful then perhaps the number of currencies used to display prices will reduce to a smaller number and make things simpler.

For the buyer they can use any currency they want transparently and for displaying prices things can only get better.

I would call this best case. There would need to be significant (likely unattainable) effort to change the standard. How many laws, signs, and code would need to be changed?
