Because of course:
There is no black market for cigarettes.
There is no black market for alcohol.
There is no black market for guns.
There is no black market for anything that’s legal! Right?
There is an incentive for black market cigarettes because (though legal) the government taxes and regulates them quite heavily, do they not?
There is an incentive for black market alcohol because (though legal) the government taxes and regulates it quite heavily, do they not?
There is an incentive for black market guns because (though legal) the government regulates them, often severely, do they not?
The pattern for the birth and growth of black markets for all of these legal products seems to be unnecessary price inflation and intervention by government, does it not?
