A thought experiment.

Imagine you are a person fighting in an anarchist revolt. You have captured a sizeable chunk of land but the front line has grown too large and you can't progress further. The state that you have been fighting approaches you with an offer: They recognise you as a sovereign (however that would look like) entity but you have to give away most of the land you've captured. They will leave you with the primary city and enough surrounding land to feed everyone.

What would be your position? Would you be willing to make a deal with the state?
