I'm not really sure what you mean by "not optional", but my interpretation is "Anyone who disagrees with the reigning philosopher-kings will be fined, jailed, or shot".

I suppose there's ostracism for a non-state solution. So if you're a business, maybe once a year you make all of your employees measure some toads, and if they can't apply a Kolmogorov-Smirnov test correctly on the first try they're immediately fired and added to a shared blacklist.

How exactly are you handling enforcement?
