And abandoning for a moment your patronising shite about "you're just scared of change", would you care to address the actual issues listed on this thread, which have arisen each of the very many times such a scheme has been implemented or partially implemented in many countries?
a) If cards are not transferrable, efficient, essential family shopping and shopping for neighbours ceases.
b) If cards are transferrable, a black market immediately arises. And actually this arises anyway with people trading purchases.
c) The cards always, inevitably, limit purchasing to participating vendors for limited services. It doesn't matter how much you sit there hoping that lots of vendors will decide to participate, this will still be true.
I could add more, like the very common problems described above of the participating vendors being shit at correctly policing what cards are used for. But let's stop there.
Because at the moment you sound like someone whining that people must be psychologically inadequate if they don't take your design for square wheels seriously.
