I think Teresita didn’t understand what “opting out” meant. As the paper said, it doesn’t mean they want no government, just essential government.

The present slim volume … explores the idea that we might ‘turn off’ the government when there is nothing useful for it to do. I hasten to add that I do not mean we should turn it off completely. There is plainly a need for government to organize foreign affairs, chase criminals, enforce contracts, and provide indivisible ‘public goods’ that the rest of us need but would not organize for ourselves if we were left to our own devices. …

Curiously enough the anarchists had a concept which was very similar to some aspects of those put forward by the Australian think tank paper. Anarchists spoke of “surplus repression” as that excess part of the state power above and beyond the quantity necessary to provide for required order. There are today in Europe regulations on how to set out your garbage, what things to say, clearances to get before being a scoutmaster. They are even considering carbon rationing coupons. And the question is, what has all this to do with government?

So the idea of “opting out” is not to turn oneself into an island, but to restore the balance between the individual and the state somewhat.
