Or in the "getting on with the business without loads of government
bureaucracy' sense either.

They can make it as bureaucratic (or not bureaucratic) as they want.
For instance, the US wanted to pre-check people going there. ESTA is
not particularly bureaucratic - they could have instead chosen proper
visas, which would have been.

I disagree. Having had a USA business visa before they were scrapped,
all I had to do to get one was lend my passport to a central London
travel agent for a day. Since Visa Waiver I must have spent a total of
dozens of hours filling in forms and having them checked at the border,
rather than just being in effect "waved through".
