It's a bit of a shame you can't use your Oyster card.

Because of banking regulations that would probably only be allowed if
the toilets were operated by TfL. However, they could accept "Paywave"
credit cards.

But the Oyster card is being used on non-TfL services!

I suppose it is, so there's been some relaxation, but still train fares.

It can also be used to pay for entry to a museum,

I'm not aware of that. TfL don't accept it at their own museum.

so it's apparently legal to use it to pay for other things than
transportation fares.

The bit which isn't legal is TfL acting as a "bank" - holding customers'
money then paying it out to third parties.

Nowadays the mere act of transmitting other peoples' money is probably
enough to involve at least brushing against some part of
money-laundering law.
