It's possible if we believe human nature to be sufficiently malleable. Why can't we all just get along. Perhaps the mountains that need to be moved for such a thing are as daunting as some of the physical laws we try to hurdle instead

There are nations and societies very different from the United States. In the United States, we can see the distrust in our neighbors play out politically, contrasted with other societies trust. You can even see it play out across various states and regions. Perhaps they’re not mountains imposed by human nature, but our perception of society.

Other nations have socialized healthcare, where anyone can be treated. Other nations have calm safe and clean public transit. Other nation’s redistribute wealth and provide strong safety nets. Other nations don’t have mass violence. Other nations guarantee retirement and pensions. Other nations trust their governments.

The fantasy physics aren’t what’s holding people back.
