The advantage of people paying by oyster isn't just reduced costs.
It's also faster journey times. It used to take forever for a long

paying cash is significantly more expensive, hardly anyone does.

So make it exact money only then. Problem solved. Works in loads of
other places in the country. Besides which regular commuters will have
an oyster card anyway because its more convenient if you travel every
day so why nobble occasional commuters?
