People who live in the USA aren't really part of the target
demographic for Oyster.

So how are people who live in the USA expected to pay for their
Underground/bus/etc. rides when they visit London?

By getting a new Oyster card when they arrive.

This isn't a plot to disadvantage tourists - as far as I'm aware you
can't buy a local e-ticket for any USA or European metro systems by mail
order, ahead of arriving there from the UK.
