If I don't let you resell something you bought that's ownership. I'm not talking about illegal copies. I'm talking about transferring the license to play the content you purchased.
If I take something back that you bought, even if I give you a refund, that's not ownership.
How about you buy a house, then when you go to sell it, the builder says you can't. Or you are living in a house that you bought and 5 years later the builder says, we are taking your house back, here is what you paid for it.
That's not ownership.
