My take also. Small "d" democrats and small "r" republicans will disagree; small "l" libertarians will see the truth but most will be uncomfortable with where it leads.
If one believes it is just as immoral to impose the will of the majority on the minority as it is to impose the will of an individual on another individual, it's hard to see how any but the smallest group of individuals can ever form a just government.
While a consitutional republic comes closest, there are unavoidable flaws, most notably in the interpretation of the meaning and limitations of national defense and law-enforcement. Someone will be given the authority to make decisions about where to draw the lines, and many citizens will disagree with whatever lines are drawn.
A closer reading would only serve to strengthen that impression.
