[Who are you?]

The "you're not buying it, you're licensing it"-argument doesn't usually hold up in court, especially not if the product comes on a physical medium, is bought in a real store, or if it says on the website "buy now" or similar.

Also some states and countries have consumer protection laws that specifically state consumers have the right to sell things they own, and you can force companies that have tied a digital product to you to transfer that tie to whoever you sell it to.
