There's an allure to the thought of a society structured around my religious ideals, but that would require such radical restructuring of every structural principle of contemporary human society that I see no purpose in trying to realize it on a large scale.
This, and of course my religious ideals are much more mainstream than yours.
I believe that we're already living in a theocracy anyway in the sense that God is ultimately supreme over all creation, and I see no reason for the fallible human institutions of the given time to further reinforce that.
