What was new was the equality of every man with the nobles and the king. Abolishing nobility was radical. Universal manhood suffrage was radical. Abolishing monarchy and establishing a republic was radical.
Most people mistake centralization as a “conservative” tendency.
Compared to the anti-federalists who opposed the constitution, our federalist founders favored a strong central government. That is why they wrote the Constitution and got rid of the weak articles of confederation.
The new government was to be strong ONLY as compared to the old one under the Articles of Confederation. It was still meant to be wan, pale and anemic as compared to We, the People, its sole source of legitimate authority. But you are one who LIKES a robust FedGov when it comes to YOUR pet schemes for controlling others, if I recall correctly, and I believe I do!
