Hahah I was waiting for that comment.
There is a difference between counting eggs in a commercial setting, and measuring stuff.
Discussion
No. Not really.
Besides, I prefer base-60.
Of course there is a difference. Measurement units are for quantities -- physical properties: length, volume, mass, forces, etc. Counting sets of discrete objects is a completely different thing.
I don't really see it that way.
In this case, it's not really a matter of opinion but of definition...
Units of measurement are used to quantify physical properties. Weight (a.k.a. mass) is a physical property. There is no advantage in using the medieval systems over metric-decimal to measure weights, regardless of whether it is the weight of a person, of a planet or of an atom. And vice versa, using the metric-decimal system is very advantageous for that purpose and to keep track of magnitudes.
I doesn't even need to be decimal. The point is having a fixed magnitude factor is beneficial for progress, which is the opposite of having to convert fractions of inches to feet, to yards, to miles with different multiplying factors at each step, introducing errors that may compound at each step.
This has nothing to do with separating commercial and daily life consumption items in convenient sets on base 12.
I get what you're saying, but, I take issue with the premise.
Day to day human scale stuff benefits from human scale relatable measurements. Using a scale that slides from subatomic to the expanses of the universe disociates the world from the physically observable, and, therefore, moves humans out of intimate contact with the world around them for a sanitized, clinical view, a godless, materialistic view of the world.
I make things for a living. I'm highly conversant with metric and imperial. There's very little functional difference between 1mm and 1/32 of an inch. But, you get built in advantages from the fractional math that base 10 measuring systems simply don't have. Base 12 is much more conducive to slope and proportions, again, in a more human accessible/scale manner.
I don't care what you use to measure things at either femtoscale or parsecs. Those don't relate to what I'm focused on.
