> We cannot be left to our own devices. We need laws to protect ourselves from ourselves. That’s what the government does.
There is no "government". Government is a collection of the same fallible individuals that you speak of. If "we" (individuals) are incapable of protecting ourselves, then "we" (government) are incapable of protecting others. Individuals frequently do both good & bad things. Same w/ the government. Yes, the government enforces child labor laws. Yes, the gov't also holds people in prison w/ out charge or trial, including torturing them, etc.
We do not need more government, we need (as a society) values that engender "doing the right thing" as often as possible.
