What has that to do with owning something you cannot download. TRy selling a 4K film you bought from Apple. Do they get your iMac as a free bonus and are you willing to also give them your iTunes account as part of the deal?
Also note, this isn't a game and neither will we be members of the EU in a few months time. Has Boris said what he'll be doing about it?
iTunes sell you the rights to watch and listen, they do not sell you the files or the content. You cannot resell these rights and you own nothing apart from those rights awatded you by Apple.
