> I'm confused, you think 12 is a better base unit to use than 10? Do you think we should all be counting in hexadecimal too?

No, in duodecimal. It's generally better: https://en.wikipedia.org/wiki/Duodecimal

And you can count by twelves on the knuckles of your fingers, so anyone who still needs to count on his fingers can still do it (I'm not certain why this is such a selling point for decimals: surely we're all intelligent enough to use higher bases?).
