Sure they can. They can implicitly assume that everybody is honest,
barring any evidence to the contrary.

That would require PAYG users to "pay the minimum possible fare
instead of the correct fare for their journey".

Only where they can do the same with paper tickets.

I don't follow this. Can you explain further?

Most Underground travelers
encounter barriers at both ends, so they will be forced to be honest.

Or jump gates, or follow others through the gates. Which would happen
in large numbers for people travelling more than one zone.

Have jumping and following been major problems with paper tickets?

It happens to me maybe 5-6 times a year, so of the order of 1 gate
usage in 250.

About half the time, I notice it happening, and stop dead on the far
side of the gate, causing the perpetrator to be foiled by the closing
gate.

And why wouldn't jumping and following not be problems under the current
fare structure?

Under PAYG-users-pay-minimum, a passenger travelling from Z6 to Z1 can
jump/follow at their first station, knowing that when they get to the
final station, they'll only be charged the Z1 fare.

Having to jump/follow twice is far more risky. People still do it, but
fewer than would if they only have to do it once.
