Not saying the state will do so however the state makes the rules. The idea that there is a limit to what the state "can" do is just laughable. Governments have murdered more of their own people (people they exist to protect) than any criminal, terrorist or foreign enemy ever has.
States are big organisations. And a lot of states were used to very bad things (I mean really bad things like genocide or willingly cause mass starvation). A state is not a good nor a bad things per se. So are corporations with which should fill the gap that a eroding state will leave, if you understood you well.
Thats exactly my problem. In contrast to a state a corporation doesn't have any ethical commitment by desgin. Believe it or not, some corporations are even using states to do bad things for their purpose! Because states (at least some) can be held responsible for not following their ethical and institutional agenda I prefer a state to a corporations governed society.
