Give me a break. First of all, under libertarianism, Obamacare and food stamps wouldn't exist. Also, heroin addicts would be responsible for their own problems, not taxpayers, so there'll be less heroin (and drug) addicts overall.
Let me explain it for you. First comes the legalize crowd. Easy step in our decadent, slothful world.
But, of course, not everybody gets his fair share. In comes the government, another easy step in our decadent, slothful world. The government makes sure everyone gets free heroin.
