Earlier quoted context omitted.
For values of 'worked for alcohol' that include 'moved world's largest criminal organisation into non-alcohol-related activity without impacting its organisational capacity one jot'.
Exactly. Crime would adjust itself, or find a new market. Compromising by legalizing something which has a purpose in being illegal is detrimental to solving the problem.
Criminals are just people. They do what is most profitable for them given their circumstances. If you legalize drugs, most of the current drug criminals will get normal jobs at McDonalds or Wall Street or whatever.
