It’s Ultimately Access
The State (with the capital ‘S’) loves its prohibitions (both the lower case ‘p’ and the upper case ‘P’). Once the State finishes telling us what we can’t do it’s up to the individual citizen to figure out what he/she is allowed to do. Keep in mind, that State wants you to believe all that you are allowed do is due to the good graces of the State. If you violate (or overlook one of many and often vague) any prohibitions you are at fault and the State is quick to respond.
Prohibitions are about control, and an easy way to control people is through denying and/or allowing access. The purpose of prohibitions (in most any form) is to keep certain individuals locked out and other individuals locked in. It is the State that gets to determine which side of the door you get to live. The State should work for the citizen, but many of the State’s prohibitions work against the citizens and deny us access, opportunity, and ultimately freedom.
