Tories' Bill of Rights

Though I identify as a market anarchist, I'd favour a codified Bill of Rights (or even a constitutionally limited government) as a stepping stone towards market anarchy. However, if this Bill of
Rights were written by Cameron, it would probably contain anti-discrimination legislation, rights to education and healthcare and other undesirable things in it. It certainly wouldn't be a Bill of Rights in the spirit of the American one. It may also undermine parliamentary sovereignty, but who cares really?
Few other countries have legislatures that can make laws in any area. Such a concept is antithetical to the ideal of limited government.
