And did I say otherwise?

I guess I took your statement, "because there's no kerning (each character takes up equal space)" to mean "no kerning means each character takes up equal space". Maybe that's not what you meant with those parenthesis.
Kerning is a table of pairs that allows them to have more aggressive advance values. For example, with a sequential 'V' and 'A', the 'A' could be moved closer to the 'V'. But kerning doesn't have anything to do with the fact that in a variable width font that 'I' is narrower than 'X'.
