You are free to consider that you are the king of whatever piece of land you want other people are also free to invade your kingdom and throw you in a cage. Human to human interactions are always anarchichal. Governmental system are just ways goups of people choose to structure their interactions. Society works by fiat even if you destroy all existing states if your neighbors get together and choose a new leader then you're right back to living under a new state. Being an anarchist is meaningless you have to pick a government structure at the very least to make sure no other government can emerge.
