We get it, you hate bicycles, they hate you too. They cycle of being dicks to each other has gone on long enough that both sides hate each other completely.
What exactly would bicycle registration achieve, other than as a punitive move? Based on mass (many registrations are based on vehicle mass since that is what damages roads) the fee would miniscule until you start tacking on the administrative costs.
Edit: damn it now I'm sucked into another one of these.
