It was made to be universally transferable, everyone has water, there is a standard meter stick in France and it was updated to the length traveled by some light so it's universally reproducible. SAme with a second, it's the vibrations of some atom, but the idea is anyone can perform the same experiment anywhere and have the same precise measurement.

The US government subsidizes farming directly, providing subsidized food and leading to industrial farming and massive lobbying.They now have lobbyists saying you could subsidize us less if we could repair our own equipment which appears as a win-win. The government (in theory) would subsidize them less, keeping them profitable and they've satiated the lobbyists keeping them happy. Appearance and actuality are all that matters with these bills, long as it appears to be helping Joe Everyman (or farmers) and kick backs their donors everyone's happy.I'm not saying it's bad, but this is the only reason farmers are being considered and the very least it can do is open the door to expand this legislation, but it'll come down to corporate vs. private interests and I don't see it going any further.
