We have the system that made sense to the people in 1792. It’s a system that is practical with their technology, and it responds to the very specific political problem they had at the time: getting 13 independent countries to surrender their sovereignty to a federal government.

That system mostly worked, but it still required a civil war to prove the Union was really was sovereign and states could not leave.

When you’re baffled by things happening over here, remember that the United States is less analogous to France or Germany and more analogous to the European Union. The individual states are more analogous to EU nations. It’s not a perfect comparison, but it’s helpful.
