Physical objects do not exist in a digital format. When I type the letter "a" is it not the exact same letter that you are using in your text? Even all the "a"s in this comment are identical, are they not?

In the physical world, no two letters "a" are exactly the same, not even printed ones.

Or do you suggest that all those letters "a" here are completely distinct from each other?

I don't think ownership works conceptually for digital stuff. There's no owning a letter "a" and there are no two letters "a" that are distinct from each other, unless you count the Cyrillic "а" which is completely different from "a".

Each of these letters "a" might be a different instance, but they are the same letter: "a". Similarly, two copies of a file are still the same exact copy. Just different instances of it.
