I'm a big fan of the idea of abolishing states, having a US national government and then county/city level governments. The states were created when it was infeasible to manage large amounts of territory due to the difficulty of communicating across long distances. That's no longer the case. We could cede some state powers to local governments and some to the federal level.
The idea would get pushback from those in smaller states who enjoy a disproportionate voice in national politics, but I feel that those voices don't deserve to be amplified over anyone else's just because they have a bunch of empty land backing them.
The People predated the States. People weren't created for the convenience of the States, it was the other way around. Now the States are just another layer of bureaucracy that people have to deal with, and I argue that giving people a larger voice in both local and national politics makes more sense than having these artificial State constructs get in the way.
