Myths About Government

I'm from the government, I'm here to help

This is the oldest one in the book! In some cases the government can help - by providing justice and protection services. In other cases only help you by robbing Peter to pay Paul. One hand in your pocket, and one hand holding out stolen cash to offer you a favor.

Governments need to restrict cryptology

Sure. So only the goverment will have cryptology in the USA? Right. This after they published the spec for DES in the Congressional Record, ensuring that every dictatorship in the world can have it, but U.S. citizens cannot. Hello, is this the home of the brave and the land of the free, or is it not?
Or they want to force companies to insert backdoors into crypto. This after tens of thousands of US government sites were hacked, for years, and they didn't even notice.

Governments need to run all the schools because...

Well... We don't let governments take over all the restaurants because some people don't have money for food. Nor should we let the governments run all the schools just because they're so expensive (in part, one would think, because the government has given a monopoly on teaching to the teachers' unions). Without tax-supported schools, many more people could affford schools of their own choice. But the real reason for de-governmentizing the schools is much simpler: schooling is too important to be left up to the government!

Freeing the schools from government control would "let a thousand flowers bloom"; a few would be dark weeds, but we have those already, and many more would flourish. This is especially true in Ontario, Canada where we have two publicly-funded school system (one being a Roman Catholic indoctrination system at taxpayer expense) with a lot of duplication.
