Fair enough.
Ultimately, if you agree with those things you should support people like Ron Paul or Gary Johnson even if you disagree with their economic policy. Neither of the two major parties are ever going to change them. And ultimately, its mostly congress that handles the budget. The President has the direct ability not to wage war and not to enforce existing laws.
I'd much rather support other third parties than the Libertarians. After all, if we are already going to break out of the major two and thus ignore the "least of the available evils" argument, why should I stop with a party that I only partially agree with?
