First past the post is illogical

It makes no sense for the state to use anything other than proportional representation. If the state is good and protects us from the the extreme demands of the market (as a social insurance policy) then it is illogical for the state not to use pr. Since the people want the state to be good then to deny them full democracy (by imposing fptp) makes no sense. If the state is helpful to the people then the people can be trusted with full democracy... which is pr. To use fptp suggests that the people do not know what is good for them in which case government itself (by democracy) makes no sense. (And only anarchy would be logical.) If democracy is logical then it makes no sense to use fptp. Only anarchy and pr are the logical positions... to use fptp suggests that (democracy and) government is good but that the people do not know what is good for them. If the people are logical then we must use pr otherwise there would be no democracy and no government. If there is (democracy and) government then fptp is illogical. Fptp is never logical if government is good then we should use pr if we are being logical.
