You have the right to expect the Moon to be made of cheese if you want.
I agree with you that mandatory registration and insurance are not the answer, but I'm amazed that you expect drivers and motorcyclists to obey the law at all times. Have you ever cycled along the A40 between Brecon and Llandeilo on a dry, summer Sunday? The slower bikes ride along some sections at 100 mph. That's where I taught all my children to ride on the open road.
We can expect whatever we want, but that's not the same as requiring it or getting it.
