Conservatism at least in our modern iteration also steals.
Your examples were leftism. Republicanism isn't conservatism. They are all leftists to some degree. Conservatists advocate nearly no governance.
Again I ask for any counter argument?
Conservatism as you define it does not exist as a sustainable stand alone structure. It naturally morphs into Republicanism/Monarchism/Despotism unless it is built upon a stable superstructure.
