What if Liquor Stores Were Run Like Minnesota's Elections?

In Minnesota, getting another voter to "vouch" for you is proof enough for you to vote. No ID required. What if this standard was applied in other segments of society? 16 States have laws like Minnesota's, where no identification is required to register or vote. These states include California, Oregon, Nevada, New Mexico, Nebraska, Illinois, New York, Vermont, Massachusetts, Pennsylvania, Maryland, Delaware, Maine, New Jersey and the District of Columbia.
Does this seem like a trustworthy system?
