Too much money and lawyers invested in the current system. I wrote a term paper for a legal history class at the U of MN Law School. It was on prohibition laws and court decisions on Prohibition in MN.

The lawmakers would write various laws trying to stop the selling and buying of liquor in various MN counties. The lawyers would find a loophole and exploit it for all it was worth. The lawmakers would eventually attempt to close the loophole. The lawyers would counter by finding some other weakness in the law just passed. This went on all through the Prohibition era.

Very interesting research this was for me.

Politics is a drug for many people. Cannot see any kind of common sensical rules and laws really working as long as all the money and power are focused on keeping the status quo.
