Property rights are not a binary, all or nothing thing, so the answer is complicated.

When do you have the right to use something? When do you have the exclusive right to use it? When do you have the right to eject others? When do you have the right to destroy it? Copy it? Sell it?

Some of these rights you may never have. Some you have the moment you pay, others are practically impossible to enforce until you take delivery.
