Brilliant! Oh, oh! I have another idea! We should tie the units together some how, like maybe the unit of volume ties to unit for weight/mass by something common, like say, water.

And eventually we could even tie them to the fundamental constants of nature rather than any master reference object.

Or we could tie them to the size of our leader's hands, which is very very small, even though he tends to brag publicly about how big they are and what that means, and repeatedly sends photos of them to magazine editors.

I'm only going for this new system if we can periodically redefine standard units, like for weight.
