If I own something then of course I can add it as a part of my property and sell it once I am selling my property.

But I can't add into my property licensed products, because it's a property of someone else, I paid a license fee and I have a right to exploit it in a way specified by the license agreement, but I don't own it, and therefore I have to talk to the licensor in case I would want to transfer the license.
