Those arguments often represent a symptom of an underlying belief about "the government". I find that many people view "the government" as this monolithic, do-gooding entity. One useful approach is to redefine it - government isn't a benevolent entity, it's a huge group of people with varying goals and beliefs, who wield lots of power over your life. Do you want those people to have that sort of access?
Well seeing as I don't have time in my life as is to run a government, to protect us from ourselves, and to make sure our system continues to run - I see no other alternative.
