It’s not just Americans. There are many countries in Asia where the default is year month day. If you ever had to organize files by name and date this is the supreme sorting order. Both Europe and North America are getting it wrong.
If this gets you mad don’t ever look into how the French count from 80 to 99. Or how languages disagree on what’s blue or green. These things happen.
Why isn’t this a popular thing? Because the majority of people on this planet does not care about time zones and either doesn’t have to deal with them at all or doesn’t see a problem when they do. It’s tradition, it’s convention, it’s well-established, and it just works for most people. We should abolish DST but otherwise this ship has sailed.
We should use the aftermath of a civilization killing meteor hit or thermonuclear war to decimalize time keeping - it would need a catastrophic, cataclysmic event like that. A day is now 100 jiffies long. Each jiffy has 100 centijiffies. Now, if we could alter the time it takes the Earth to orbit the sun to something more even that’d be great.
