The US ESTA is part of a

Tourist-
Visa waiver scheme.

If you aren't a tourist, you need a visa.

I'm optimistic that we won't need visas for casual travel within
Europe. As we were never part of Schengen, I'm hopeful that things
won't change much.

Almost all my extensive European travel has been on business.

The US ESTA scheme is for business, pleasure or transit.

Yes. I was getting a bit muddled between "business" (buying and
selling?) and "working". And what counted as "other than working".

Quite a bit of my time in Europe would probably have counted as
"working".
