So the issue stopping NFC abuse is the policing of questioned payments? [i.e. someone with a auth key can basically choose to charge people what they want (by using modified aerials), it's up the the people charged to complain sufficiently to get that auth key revoked] I'd imagine that there might be a low bar of complaints to get a key revoked, but perhaps a higher bar to start legal proceedings?

The problem is, that if you just wire an aerial to a legit payment terminal and point it at people, it will probably pick up more than a single card, in which case, it won't charge anyone. The use case for that is extremely limited.
