Enslavement of some to the will of other men is evil as well. So how do you justify using the power of the government to enforce your notion of what is good and proper on those that don’t agree with you?
The libertarian view of if leave each other alone will be fine. Again what about drugs that right now you can only get with a doctor’s prescription. These drugs are legal but there is a thriving black market trade in them. Wouldn’t people demand access to them too once the other drugs are legal. If you don’t think they will then you don’t know addicts. One area for sure were it will make things worse is on our medical system which will see a spike in addicts. The irony of libertarians defending drug use and addicts is that they are the totally opposite of the libertarian ideal of letting everyone do want they want as long as it doesn’t brother anyone. Addicts want they want and they don’t care who they have to walk over to get it. In my view crack, meth, herion and drugs like that should never be legalized because of the effect they have on us all no just the people who use them.
