Earlier quoted context omitted.
In a democratic society, "they" are the majority. You are a part of them, but you get your one vote and no more. They can bind you without your explicit consent, because at the end of the day they are the ones who protect you from the dangers of other nations, anarchy, etc.
The majority of whom? Do you think the majority of the world would vote that they need a visa to travel to, say, the US? Also, there's no need to protect me from anarchy, since the exact meaning of the word "anarchy" is "no rulers". I'd rather be protected from _rulers, than from lack of rulers.
Re: anarchy, it's a cute philosophy for sheltered westerners who grew up with the blessings of good government. Ask anyone in rural Pakistan, where government power is almost nil and warlords dominate, what they think of anarchy.
