Agree. There are many organisations that put drones to good use, and they will have not problems registering.
There was an incident with a drone over a nuclear power station a few years back. The authorities were very concerned that it may have been a terrorist organisation doing a recce of security. There have also been several instances of drones being used to pass contraband into prisons, in Britain and the US. The contraband has been mostly drugs, but larger drones could also bring in guns. However, people who will use drones for criminal use will not register.
By making registration a requirement, it will keep drones off of the supermarket shelves. It will also make people get 3rd party insurance (not a bad thing) .One of the problems is not just the 'idiot' users but parents who buy drones for kids, where the child is not old enough to be responsible (a parallel with air rifles perhaps). An example might be that no-one would dream of taking a fixed wing model onto a busy beach or promenade, but a child with a drone might well do.
There are several factors driving the move to regulation. Safety, security, and public nuisance (incl. privacy). Unfortunately it looks like RC model aircraft will fall under the same regs, but many of those affected are already in clubs. On the upside more people may [edit] not now join clubs, and if there is a drone division of the club, people may well migrate to other forms of RC flying
