Family units, tribes, fiefdoms, kingdoms, religions and governments all evolved from anarchy. Humans crave order and constraints, and a bit of hierarchy. Thus if you leave groups to their own devices, they make rules. As the group gets bigger, they break into factions based on what they care about, and fight for different rules (politics). But that's all about order. So anarchy is an unstable element, and it evolves to a libertarian state. And one faction always wants more government/authority than what we have, and another wants less.
Left and right are inverted terms in Europe and America -- but in America, the left is the one that wants elitists ruling the rest and more centralized power, and telling us what to do, for our own good. And the right is the group that wants less authority, more religious freedom, more free speech, less regulation, and so on. They do have issues they cross on -- the left wants less consequences for breaking the rules, and the right is about more order and consequences. The right also can cross over and want rules on morality that align with their religious beliefs -- but the left has plenty of those too (like environmentalism, social justice, redistribution of other people's wealth, and so on). But as a general rule, the more leftist places in the country are trying to micromanage people's lives, and the rightist places more want to leave people alone at the federal level, and even at the state and local levels.
