I think you're reaching quite a bit with this comment. The people who drafted the constitution actually pushed for a Federal government that was larger far more powerful than the previous Articles of Confederation did. And they continued set up precedents while they were in office for a larger and more unified government than many of the States likely expected. They also recognized that a modern Democracy was a bit of an experiment compared to the rest of the world and were unable/unwilling to make it too large too soon. And most of U.S. history seems to agree with this approach and it shows that a large open government is less likely to be abused than a small government which can be captured and rigged by a few groups or even individuals. It's the separation of powers between branches of the government, more than the size and powers of the Feds vs. the States that helps to limit the chance for dictatorship.
