Well for the sake of argument, america the greatest country in the world, metric countries not the greatest countries in the world, sometimes it makes sense to not be like everyone else. Also britain has been shifting slowly back to standard and has been teaching it again in schools, russia is also slowly bringing back their own standard measurements( which is a mistake their standard was more similar to germans standard, which was miles apart from british and roman standard) Also other countries in the world still use standard measurement even if their official measurement is metric, go to any european country and you will hear a weight or length measurement that is unique to that country, that people use themselves daily outside what the govt mandates.
Another thing with standard, standard for imperial is based off of roman measurements, a british mile and a roman mile were almost identical, many measurements were almost identical or atleast close, and both used a base ten system. The major advantage of base 12 is that it can be used without precision equipment, there are still roman mile markers in europe, and they are very close to actual mile markers, things like the colluseums and the pyramids were built with a base 12 system, and even today base ten countries need oddball construction sizes because base ten never cut it for construction.
