Really? Are you saying you can't get totally private health treatment if you want it?
Have you got a choice who supplies your water? A real choice which train operator you would like to use?
Perhaps you think the energy supply system perfect. With companies ceasing trading every other day. And being bailed out by the rest of us.
Even with shopping, much of the real choice that once was has been wiped out by the giants.
Not to say there aren't some things that are improved by competition. Telecoms being the obvious one. But rather difficult to have a genuine choice of local hospitals.
