In these days of "Environmental Enlightenment", many would see ticketless
travel as a resonable goal. I guess its just that "registered" bit that
causes trouble, what is the official reason for it over a scheme where you
could *choose* to register for added protection if you wanted?

Just a guess, but probably because they fear being besieged by clueless
unregistered cardholders wanting the added protection retrospectively.
