This case has nothing to do with what you mentioned above, unfortunately:

This is a student of a local instructor. This wasn’t someone that just showed up and was left to their own devices.

The club has rules and policies in place (such as a waiver and a club membership requirement to fly), and those are being actively ignored.

If the club collectively doesn’t give a crap about those rules and policies, then tear them up – I won’t stand in anyone’s way. But let’s not pretend to care about maintaining an active and safe flying environment if we’re going to rationalize away this stuff when it keeps happening (over and over again).
