That is comfortable suburban armchair extremism.
You live in a nice neighborhood, patrolled by city police, making your coffee with municipal water, kept safe by a government run military waiting for your mail to be delivered to you by the Postal Service.
Pack up your stuff and move to the Congo or Darfur of some other dystopia without a functioning government where you have no one to protect your property rights or roads to drive on or water to drink. Where you are at the mercy of thugs and warlords and live there for a year and tell me about your anarchist utopia. It won't be as pleasant as you think it is. It's easy to talk that guff from the pleasant suburbs.
There are things we handle as individuals.
There are things we handle at the local community level.
There are things best left to the states.
And there are things of size and scale and risk that take a nation-state to address.
Somethings might even take a multi-national approach to solve.
I don't want to live in a Mad-Max lawless dystopia any more than I would want to live in the Soviet Union.
Extremism at either end is always the wrong answer. Real life involves complex and imperfect compromises. There are never any easy answers, only trade-offs.
A certain level of government is necessary to maintain the comfortable life we enjoy.
