Yes, but the states have a sovereignty that is equal to each other. They aren’t allowed to make conduct illegal that occurs in other states. Even if it was legal it’s not part of being a cohesive country.

The post I responded to originally implied that having the federal government enforce standards would lead to “The long term disintegration” of the country. I am pointing out that without the federal government enforcing standards we are already seeing states set up a long term disintegration of the country.
