Did early humans own the tools they created? Probably. Government limits this in almost all cases. Even the liberty minded founders of the USA created eminent domain which is not limited in which property the state can take, technically. The USA typically is supportive of private ownership, but not the originator. I think ownership exists inherently in humans. As does it's counterpart theft. We have decided that theft is bad and ownership is good over the millennia. It is possible we may change to not value ownership and theft would then have a more positive connotation.

Business cannot exist without two parties transacting. Businesses can exist without ownership. That is if you do not consider a persons labor to be "owned" by them. There does not even have to be capital exchanged. Bartering for labor can and does happen.
