As it stands, you have the criminal justice system attempting to shut down all behavior using the coercive police power of government. This is the strongest force that government has over the people: depriving citizens of life, liberty, or property. Legalization means allowing the people to choose to engage in an activity, thus shifting to the permissive oversight role of government. In this case, the citizen has the implicit trust of the government in that he may act as he chooses toward the previously-banned item. If this second route involves more parts of government, so be it, but at least it returns some autonomy / choice / liberty to the individual. Depending on what politicians do, we may be stuck in a bad in-between state where you have the full police state going strong to prevent non-authorized dealing as well as the oversight / regulation function. I fully trust that the politicians will continue to pursue power at any cost, including the liberty of the people and the sovereignty of the nation.
