I cannot because I am under the impression that for the most part Libertarian philosophies haven't been implemented on a wide enough scale in any country to satisfy people who believe in them. This may be part of the appeal to some people to see such a system attempted. And it is definitely a common reason used against such a system. Ask yourself should we (as human beings) be against systems which have not been implemented yet? And if so how do new systems come into existence if we are?
