Personal property did not depend on trusted third parties
For most of human history personal property did not depend on Trusted Third Parties (TTP). To the extent that TTPs were needed, was to defend property from depredataions of other third parties.
Jewelry, automobile keys, house keys — these all show that humans had a preference for having sovereign access to their property, without relying on third parties.
This preference remains with us today and you can see it manifest itself in people's anger when they discover that part of their product is not owned by them.
