In reading and debating liberty with other people, I notice that almost every argument against freedom, at some point, boils down to consequences that we currently encounter because of government interference.
The reason national borders are "necessary" is that the state steals money in order to finance welfare, which is then either a nice carrot enticing people who want something for nothing or is a nice excuse for xenophobes to use against immigrants who want no handouts (most of the people in America who want something for nothing are not recent immigrants).
The reason gun control is "needed" is because government has made it safer to be an aggressive criminal than it would be if self-defense were not criminalized. It also causes people to be unfamiliar with the safe handling of guns resulting in more accidents than would otherwise occur. Both crime and accidents are then used as an excuse for more victim disarmament "laws" making a crazy feedback loop.
Driver's licenses and draconian state control of the roads are "necessary" because we have foolishly allowed the state to assume ownership over the roadways.
The reason the "War on (some) Drugs" is "necessary" is that prohibition causes an inflated profit margin and makes violence inevitable.
The reason "healthcare reform" is "needed" is because of the "War on (some) Drugs" making remedies expensive and (legally) dangerous to try, and because of government licensing and regulation of doctors artificially causing a shortage of healers.
The reason "gay marriage" is an issue is that government has been allowed to immorally declare it owns the institution of marriage, to be rationed out as it sees fit.
The list goes on and on. Government causes the problem and fools gullible "patriotic" folk into pointing to the problem as a reason they need government. I'm not the first to notice the pattern:
"Government is a disease masquerading as its own cure." - Robert LeFevre
Well, I don't need government for ANYTHING. And neither do you.
