Freedom of expression, association and traversal works brilliantly in a representative democracy (republic) wherein the voting block is decentralized between states. Within the USA, counties should have the sovereignty to break off and join whichever state is the most aligned to the county's principles. It is logistically possible due to modern communications and transport infrastructure. It would serve 2 main purposes: 1. Incentivizing neighbouring counties to strengthen their cooperative diplomatic ties. 2. Incentivizing states to align with their county values.
