When someone "selfishly insists" of his/her "freedom" then government is already entitled to know the best how to make it. Arbeit macht frei!

Are you really equating traffic signals with Nazi Germany?!

Look, you can't have civilization without an underlying system of laws. As society becomes more complex, "somebody" has to take responsibility for those rules. Who should it be? History seems to suggest that some sort of democratically elected government seems to work best. Not perfect, but the best results so far.

I'd also observe that people who go on about "freedom" seem to ignore the fact that they themselves rely on the system of rules that they profess to despise- especially people who live somewhere like New York City. For example, think about your absolute requirement for foodstuffs brought into the city because you can't grow your own. How does that work? It works because millions of people between the farm and your favorite deli accept and agree to rules about commerce, sanitary food transport, payment terms and heaps of other government-overseen protocol that most of us take for granted as we go about our daily lives. Without it, you'd starve.
