Can’t you just log locally on the charger the transactions? Once the connection is restored and if there are dishonest charges you can just pursue them the same way a petrol station would pursue those who fill-and-dash.
Or even better. Can’t the car download a certificate from the central server when it is still up which is signed with the private key of tesla and it contains what level of service the vehicle is subscribed to and an expiry date? And then the charger can check the validity even without a network connection.

There is no "service" for charging, it is just like with ICE cars at a gas station. You fill up your car, and then you get charged for however much you filled up.

It sounds like you don’t need to swipe your card every time. The system has your payment details on file to pay. That is what the certificate would attest to.
