The act of registration is simply a form of control. When control comes from the government it is always, ultimately, enforced at the tip of a gun. The granting of a clean registration gives you “permission” to proceed while denial of registration denies you from whatever “it” is that you are wanting to do. Can you do “it” anyway? Of course, but then you are in violation of a statute or law.
But why must we register to exercise constitutional rights? Many of them are held as “self evident truths” granted by God himself? Why do we allow government to control that which we say is “endowed by our creator”? What is the criteria by which some rights require registration while others do not, and more importantly why?
The proxy for registration is “free”. Anything free from the government is only available as long as the government says you can have it. But again, why make some things free but not others? Why isn’t food free? or housing? Certainly they are just as critical as healthcare.
