There's a difference between owning something or renting it. When you rent something, there's a contract you sign that specifies what you can and can't do. You generally expect the owner to have the technical capability to enforce the contract in case you breach it. But when you own it, then no one else should retain any sort of control over it, period. It's yours only. (You obviously don't own something if you got it on a loan, not until you paid it off.)
