Stupid DC Laws

Last week I was in California and bought four bottles of wine to be shipped home. En route home I got this email:

When you placed your order last Sunday for a total of 4 bottles to ship to Washington DC, I didn't realize at the time that DC has a shipping restriction whereby we can only ship 1 bottle per month to an address. Therefore, we cannot ship your order from Ridge.

Only the DC Council could create such an incredibly stupid law. Out of state vineyards mostly don't ship to DC as they have no way of tracking the number of bottles to be in compliance with the law. What is the point of this regulation? I am at a loss, but I think that it has public health controlling Catania's handprint all over it.
