That said, libertarianism simply does not work well in the modern world. If you want to live in a first-world democracy, then you have to be willing to pay the higher effective taxes, put up with the strong regulation, and accept the social safety nets that are part and parcel of a modern first-world democracy.
On the other hand, if you spend a great deal of time in third-world nations, you come to realize what happens when the government has lower effective taxes, weak regulation, and little or no social safety net - all of which are part of libertarian and conservative thought. The country can still work, can still get along, and can still prosper to a significant extent, and for those who have money, life is great! BUT for the great majority of the people, life is hard...and they will never, ever have the general standard of living that we enjoy in first-world democracies.
So you have to make your choice - do you want to live in a first-world democracy, or do you want to live in a third-world nation...because all first-world democracies have higher effective taxes, strong regulation, and a significant social safety net, whereas (with a few exceptions) all third-world nations have low effective taxes, weak regulation, and little or no safety net. Which is better?
