I'm not 100% sure how that works. I'm not sure if the local shoe store got a letter or an email or whatever, but they shut down. I'm not sure we would get something similar or if they would simply allow Iowa businesses to determine themselves whether they fit into those categories. I would agree that it would basically not change anything if they were relying on businesses to actively shut down themselves.
I've seen alot of talk about potential liability-- how about the liability to the State of Iowa on their uniform enforcement of their policy? If Business A is shut down and loses millions in revenue, but Business B is allowed to continue, there will be lawsuits. To be fair, this shouldn't be the primary consideration, but people are talking liability in the businesses sense, how about to the State?
