Chris Angelico asked: what does a negative string look like?
This is a very good question. It looks a bit like a negative number.
They really don't. Negative numbers are well defined in terms of being
the additive inverse of natural numbers. String concatenation doesn't
have a well-defined inverse, as you demonstrated by not actually trying
to define it. It strikes me that following this line of reasoning is at
best a category error.
