Re: Polices the irresponsible, perhaps: not the wicked
Flying into a plane engine deliberately would be very difficult, although not completely impossible.
You are right though, none of the bad things can be stopped by technical rules or import bans as the technology is used everywhere.
Maybe the idea is to add anyone to the monitoring list who buys drone parts without also having a licence, but given you could use a mobile phone as a flight controller with a suitable USB interface board, I'm not sure that will really help.
