Wolf says wine industry groups have every legal right to try to change direct shipping laws. But he objects to businesses that openly disobey or ignore the law. Wolf also points out that alcohol is different than other products subject to interstate laws. The courts treat it differently, and the Constitution treats it differently. So, it doesn't fall under the interstate commerce statutes.
Wine is alcohol.
Yes, there are problems with the system in place, but it's worked pretty well for 70 years. If you want to change it, do it carefully. But in the 12 reciprocal states, including Washington and California, alcohol sales aren't like the wild West. State officials still have control over distribution. People selling to minors are still punished when caught, and the three-tiered system still rules the day.
