The issue with remote piloted craft is that those that are serious about it will do the work to train and certify accordingly. The rest just don't understand why they need to be regulated and expect everyone else to accommodate them on the basis that they have decided they are "the future".
Without proper enforcement, the rabble will continue to disregard regulations and put others at risk as they simply do not understand the environment they are entering.
The best avoidance system will be for the operator's controls to discharge an exceedingly large voltage into the operator should their craft enter restricted airspace or get within close proximity to an actual aircraft.
That may work
