But classical liberalism is more than just economic liberalism. It's individualism, equal rights, separation of state and church, religious tolerance and much more. It's certainly not about using your wealth to gain power over others, to infringe on their liberty. Not even the government can do that in classical liberalism - if it breaks the social contract, it becomes a tyranny to be overthrown. No monarchy with those guys. Economic protectionism or subsidizing your coal industry buddies are very much not economic liberalism either.
