Beer is good. It's an opinion based on serious research. A lot of beer laws are not good. They often restrict beer distribution, limits sales, and generally make it harder for us to access good beverages.
There have been some benefits of these restrictions. The main one, probably, is that it provided the storyline for Smokey and The Bandit:
Big Enos (Pat McCormick) wants to drink Coors at a truck show, but in 1977 it was illegal to sell Coors east of the Mississippi River without a permit. Truck driver Bo "Bandit" Darville (Burt Reynolds) agrees to pick up the beer in Texas and drive it to Georgia within 28 hours. When Bo picks up hitchhiker Carrie (Sally Field), he attracts the attention of Sheriff Buford T. Justice (Jackie Gleason). Angry that Carrie will not marry his son, Justice embarks on a high-speed chase after Bandit.
(Note that IMDB's description — "The Bandit is hired on to run a tractor trailer full of beer over county lines in hot pursuit by a pesky sheriff." – seems to have confused the film with the Dukes of Hazzard. Crossing state, not county, lines was the issue and Rosco P. Coltrane was not part of the Bandit films. I digress.)
In my home state of West Virginia, getting craft beer, until 2009, was hard. Beer with more than 6% ABV could not be sold in the state. All beer in the state is "non-intoxicating beer" but the definition was raised from 6% so that it now includes (and allows) all malt-based beverages between 0.5% and 12% ABV.
