A payment is a public ranking contribution, not ownership of a person or animal. The ranking boards intentionally launch from zero, so a board begins empty. A contribution that later appears is still only a public line. It is not a title over a person, and it is not ownership of a life.
Human doors include control and removal for the named adult. That control remains with the named adult even when a board starts at zero, and even when a public ranking contribution is paid. The listing can be public; the named adult can still control or remove it. Ownership of the person does not follow from the payment.
