From The Heartland Institute:

Big-Government Booze Blues

C. Jarrett Dieterle, director of commercial freedom policy at the R Street Institute, says blue laws and other regulations on consumer alcohol sales are a legacy of twentieth-century government paternalism.

“These are all, by and large, outdated laws,” Dieterle said. “A lot of these retailing laws that restrict how people can buy alcohol are all holdovers from the immediate post-Prohibition era. The federal government got out of the booze-regulating business, and states rushed in to regulate and started enacting a lot of these laws to control people’s access to alcohol in different ways.”
