In the absence of any state holding the monopoly of power a large corporation automatically grows into a defacto state as the British East India company did in India.
The British East India Company was a state-supported group, so it doesn't count. But you're right that in most cases there is a winner-take-all dynamic to coercive power, so we're going to find a monopoly of force and a de-facto state. This is not inevitable though; for instance, forager tribes in general manage to do without, as did some historical stateless societies, e.g. in medieval Iceland. Loose federation of well-defended city states is an intermediate possibility that's quite well attested historically.

That wasn't the argument I was making. The argument I was making that in the absence of a state that holds the monopoly of force any organisation that grows really big is going to use coercive power and become states-like.
