This objection is sometimes raised, that anarcho-capitalism might not work because someone (who is wealthy?) might just try to create their own State, and anarcho-capitalism won't be able to prevent this.
I don't think this is a problem unique to anarcho-capitalism though, currently States are subject to secession or becoming worse, so anarcho-capitalism can't prevent a State from forming much more than the State can prevent being dissolved. There's somewhat of an equal problem, it seems like.
What are your thoughts on this objection that anarcho-capitalism can't work because it will just form into a State or State(s) again?
It doesn't, Anarchism is a moral foundation that allows me to reject such liberty-violating construct by violence (self-defense is always in effect when dealing with state agents).
