A government is a body of men most notably ungoverned
Shepard Book
What a government is is the intersection of every influential group in a country. In a country where there are massive amounts of poor people that do nothing but breed, they will not have any part in that government; give that mass of poor people the vote, and a reason to use that vote, such as welfare, and they are part of the government.
If you as an individual don't have the power to make yourself part of the government (theory of voting, public speaking, bribery, blackmail, specific knowledge etc), then you do as you say and give up individuality to "join" a group that does.
This cancer has metastasized a long time ago and it's already devouring humanity, just look at the crises that are happening around the world: financial, economic, political, military, enviromental, health, etc....
I can't even imagine how good would a world look like where individuals would not give up their self-ownership. I guess nobody does. But I know that it would be a better world.
