Don't conflate zero with the empty set {Ø}.
Numbers are abstractions, and zero {0} is when you simply take any amount (even negative amounts) and subtract it by itself.
There's even a history about, in positional numbers, where they used empty spaces between numbers which today are 2,016, they'd use something like 2_16 or 2 16, which could be problematic because what if the number was 20,016?
