The proper role of government is exactly what John Stuart Mill said in the middle of the 19th century in "On Liberty." The proper role of government is to prevent other people from harming an individual. Government, he said, never has any right to interfere with an individual for that individual's own good.

Most of the energy of political work is devoted to correcting the effects of mismanagement of government.

I am a limited-government libertarian.

You cannot simultaneously have free immigration and a welfare state.

To the best of my knowledge, there has never been a monetary union, putting out a fiat currency, composed of independent states.

I know of no example in time or place of a society that has been marked by a large measure of political freedom, and that has not also used something comparable to a free market to organize the bulk of economic activity.

The way you solve things is by making it politically profitable for the wrong people to do the right thing.
