Sure, but what _is_ the practical solution to the invasion of a foreign military power on your home soil then? Do you think these systems should only be developed by the government? And if so, do you then apply the same logic to anyone working in the government?
Idea. They can develop all they want, only the government should be the one buying and selling weapons. That way if a government decides to sell weapons to genocidal maniacs, people can vote that government out.
