Why create prohibition for an age and then spend money on policing it? It clearly doesn't work as people do what they want if they really want to. Making it a part of society and not something that people should be ashamed of can again create issues. Spend money on the health and education aspects and not the policing, which is what would have to happen as putting the price up on something makes it a commodity for theft. Liquor store owners are going to have to start carrying guns with this sort of policy.
