Corporations are just legal agreements. There is no need for the state to be involved for them to exist, though of course it helps the formation and preservation of corporations that a state exists to enforce contract law and protect the right to person/property, but that equally applies to any legal agreement. The only extra-contractual benefit the state grants corporations is limited liability for tort.
