I'm talking far future. Also I agree that social Conservatism is going down. The only reason that you are right about the fact that Libertarians should be glad about the downfall of Social conservatism is because there is to many social Liberals.
I wouldn't be so sure. Remember that in many parts of the world social conservatives/reactionaries are gaining ground. Most Muslim countries for example, in Israel, in Eastern Europe, arguably in East Asia. Theirs no inherent reason it can't happen in the USA.
