Once again, you conflate making a copy with moving a physical object. No. The file is not akin to a book or a vinyl record, it is a message. When you “move” a file, then you are modifying one media to contain the same information. It is not like taking a page out of a binder and putting it into a new one, it is photocopying that page and putting the new copy into the binder. The original is still there. It can still be used.
Never mind that your example is absurd, as any commission for work does include all rights to make copies. Or is it that absurd? I ran into an example similar to yours was a play script, where the publisher wanted to force any acting group performing that piece to buy a script for every actor. Sheet music is much the same, where publishers make dire threats to anyone caught photocopying the song instead of buying a copy for every choir member. Not much different from your USB example, really.
