The crux of every argument for government is that government prevents chaos. Chaos is marked by unfairness, strife, misery, suffering, violence, instability, inequality, and above all else, the absence of principles. Look at our world, identify the primary situations you see chaos, and get back to me on how government prevents them.
We have gangs of highway robbers beating and killing people. Half of all wealth is stolen every year by the largest cartel of violence known to man. Children in countries nowhere near us are being bombed and their parents are picking up arms against us. Citizens who disagree with thieves are targeted by their enforcers using tax code as an excuse to lock them in rape cages. Even the veneer of democracy has been shown to be completely disposable to those in power. Banking cartels steal money by inflating the currency in order to fund further corruption and war. Less than half of all violent crimes are solved while our prison system is primarily populated with nonviolent people. Children are forcibly indoctrinated by government schools in order to instill a trust in the very government destroying their world.
Government is the belief that some humans deserve special rights, including the ability to take rights away from others. This is the epitome of randomness, unfairness, inequality, and chaos.
Government is a centralized and subsidized organization of systematic chaos, and agents of government are agents of chaos.
