LOL Peggy, if you're happy with bland mediocrity and willing to "fight against these people" who believe in a more individualized opportunity, then by all means let a centralized government rule every aspect of your life. But wishing it upon everyone else seems a little mean spirited dontchathink? ;-)
The marketplace can promote plenty of bland mediocrity on it's own and it can impose it pretty well and frankly be plenty intolerant of true human individuality.

Have you ever contemplated the irony of self-styled liberals usurping the concept of libertarianism, stealing it's name and then turning it's back on the ideology?
they are mostly probably civil liberties people, and they have as much claim as anyone to civil liberties.

Everything outside the realm of interstate commerce, foreign treaties and national defense. Those are the only reasons a collection of sovereign states would gather together as a collective entity.
why even have that? Why gather together as a collective entity for that but not to address the fact of say excessive smog from one state which just pollutes as much as it wants, ignoring all state boundaries, and rudely crossing into and polluting another state?
