Maybe things have changed, but in the US it used to be a question of when does a digital file “exist”. The law was: when you buy a digital asset, the first time that asset is instantiated is the one true version of the file. To sell it you MUST sell the device where it first appeared. So you have to sell the computer, phone, or tablet that was used to download it. Maybe that law has been revised.
