“Democracy is the worst form of government, except for all the others.”- Winston Churchill

So, at the end of the day, who is going to maintain and enforce those inalienable individual rights? What happens if I trample on your individuals rights?

In regards to laissez-faire capitalism, how do we handle externalities?

Overall, I don't think I agree with your conclusions that support t for a democracy requires support for other highly nuanced interactions.

Its as if you are saying:
Well, if you like ice cream, you must also like gelato.
If you like ice cream, you must also like sorbet.

Overall, it seems like a weak analogy in a world where details matter.
