Why would separation of powers make anti-federalists happy?

The separation of powers would make anti-federalists happy because it limits the concentration of authority within a single government branch, thereby reducing the risk of tyranny. By dividing power among the legislative, executive, and judicial branches, it ensures a system of checks and balances that protects individual liberties and state rights. This structure aligns with their concerns about a strong central government overpowering the states and infringing on personal freedoms. Ultimately, the separation of powers reflects their desire for a decentralized government that is more responsive to the people.
