I think almost everything important that's ever happened was unimaginable shortly before it happened. Good things and bad things: ending slavery, ending child labor, women voting, etc.

Breaking the United States up into a number of pieces could be very good for the integration of those new nations with the rest of the world and the international law whose primary enemy is now the United States government. I think that it would be very good for democracy, for people to be within some hundreds of miles of their nation's capital, as they are in many other countries, so that they didn't have to travel thousands of miles to protest, to exercise their First Amendment rights, but that is the current state of affairs in this overly large, imperial nation.

The United States is a rogue state violating international law in many, many ways that California wouldn't have to if it seceded and became a nation.

Slavery remained in the Deep South by other names - in prison programs with charges over nothing and eternal debt that threatened every African-American in the South right up through World War II. And that was after killing three-quarters of a million people, destroying cities, and creating hostility that exists to this day over the the Confederate flag and the racism it symbolizes, all brewing out of bitterness over a war that didn't have to happen.

The United States has been becoming worse year after year after year for decades, and it's guaranteed to continue down that path if we don't change something.

Climate change is so unimaginable that most Americans deny it's happening.

No other nation killed people the way the United States did to end slavery.
