On a philosophical level, you can own the land, if you create it. If you put work into it, you can use what you get, but not own it — eg. as a dog trainer, I put work in training your dog, and I can use the results, but I cannot kill it, because I don't own your dog. This was outlined by Pierre-Joseph Proudhon in his works about land.

On a practical level, you are free to do whatever you want, if you don't interrupt my freedom and safety — otherwise, by NAP, you are starting the aggression. Killing the land where I live (while you yourself may not  be even close to it), because you bought it (from who? planet Earth? or prevoius owner, who didn't have a right for it either?), thus, poisoning my life on it, is interrupting my freedom and safety. You can kill your company, fictional character or a project — because you really created it, and you do own it.

I have this mythical utopian fary tale of anarchy, which actually exists in or have existed in Ukraine, Spain, ​​Kronstadt Commune, Xinmin Province, Oaxaca (20th century), Seattle, Christiania, Zapatista Students, Munster Anarchio-Communist Commune, Kurdistan, Zaachile, Cheran, Aura-Amba, ZAD, Fiume Free State, Strandja Commune, Markov Republic, Amish territories, countless indigenous peoples (e.g. Bushmen, Indians, Hopi, Croatans, Cherokees, Anuaks, Nubia, Piao, San, Santals, Tivs, Zomis, etc), and other territories. 

Where does your real non-mythical truestory existed, so we can check, if it even works in practice? I presume, it should have a lot more practical examples than some fairy tale
