It's not universal. Not everyone in the universe uses it, therefore, it cannot be.
Base 12 is superior to base 10 for every day use. Just because we Americans are idiots, doesn't mean we can't be right about things on occasion.
I also prefer EVERYTHING to be decentralized, which, includes systems of measure. Centralization of weights and measures has been a long road to centralizing authority, culminating in the CBDCs we all abhor. Just because it is convenient does not make it better to have a completely cohesive set of weights and measures.
Decentralize EVERYTHING. Build bridges when necessary, but, keep them small and kinda rickety.
