More on point, this is what I believe:
The U.S., the World, The Universe, The multiverse, however large a unit we want to define as the overseeing government body, needs to have minimal regulation.
Currently the US gov. needs to have less restrictive laws and do what was initially intended. Let communities decide their laws.
Hundreds of millions of people cannot agree on, let alone live by, specific sets of laws. Specific laws (ie. drinking age, legalization of drugs, gun ownership, etc) need to be set at smaller levels. This allows people to have input, which they crave more than outcome a lot of times, and a choice.
If certain communities allowed certain behaviors, and you want to engage in that behavior...go there (Prostitution in Nevada for example) . If certain communities don't want a behavior, and you don't want that behavior, go there (When DC had banned hand guns, for example). It's free market economics applied to government. It's what was intended. And it's really the only feasible solution for everyone to get along.
