whose primary functions include reproducing itself
Mind expanding on that since it seems like in the us its doing a piss poor job of it. In fact I'd say that a capital dominated state wants to do away with itself via privatization.
Engle's makes a pretty convincing argument that the state arose to mediate class conflict in favor of capital and that it cannot be destroyed until that class conflict is resolved.
Take the landlord tenant relationship. In order for this to exist then the landlord must exercise their property right through state mediated violence and the tenant is offered some rudimentary protections. If the state simply no longer recognized the property right of the land lord the state would wither and class conflict would resolve a bit.
