There's a different thing for that: tabulatures.

Tabulatures come with their own limitations though. They're mostly a far less portable way to express western music. They also lose a lot of meaning. Is a note part of a particular chord or melody line? A lot of this is not visible in tabulatures.

The point of OP was that sheet music is general and portable, but it really is not. Tabulatures make the Position you play on a guitar unique, but, again, are not portable.
