Perhaps the UK should pass similar legislation and simply make it an offence to own or operate a drone without ADS B? The cost to the operator is low and it would make prosecution for illegal use much more clear cut.

ADS-B frequency is already saturated adding more than a million sUAS transponders will make the system useless for all users. And like legislation, geofencing, registration etc etc, will only apply to those who want to be cooperative, There are no primary radars currently in use that will identify a 'drone' - it would require all airports to re-equip purely for defense against malicious drones.
