I wondered if there was a way to 'opt-out' of all these government rules and regulations so freedom can be restored.
Eh... ok, look, ask a pot smoker. Ask someone who wants to be married to three or four women. Ask someone who feels that private property is unnatural and s/he should have equal access to anyone else's possessions or lands. Ask someone who thinks they should be able to kill another person who tries to take their possessions. Ask someone who likes to drink beer while driving. Ask someone who's a stock broker and feels they should be able to call a friend in industry and get some tips on when to sell or buy. Ask someone who wants to fly their unregistered drone around, or doesn't like anyone in the government knowing they own a dog. Ask someone who feels compelled to eat other people (stick to corpses...no harm to another living person, right?).
Ask any of them if they've found a way to "opt out" and "have their freedom restored."
Let's say I wanted to buy a new gun. Let's say I didn't have a particular ID for the state I want to buy it in (like a gun show or great sale across a state border).
Technically I cannot buy one because I do not have that particular state's ID.
Ok, so technically you can't buy because you are not a RESIDENT of that state, not actually because of the ID. IDs just make proving it a little easier. And that only applies to handguns. Long gun sales, from a dealer, are perfectly legal across state lines. AND, if it is a handgun you can still buy it and have it sent to your local dealer in your state to do the transfer. But anyway...
And getting someone to buy it for me (so I can enjoy that great deal) is illegal so I cannot do that either.
A lot of this seems unnecessary. And appears to have a money motive involved.
It seems unnecessary to you because it IS largely unnecessary from a practical viewpoint, for the vast majority of folks who would do those transfers.
However, the people of the country, via their legislative representatives, decided back in 1968 that it would be an acceptable restriction on freedom to make sales like that go through a system of federally licensed firearms dealers -- the point being that it would catch some folks who were trying to buy guns when society had decided they shouldn't have them.
People voted, legislators made laws. Here we are. Every law, ever, is a trade of somebody's freedom to do something in exchange for the promise of something else.
FYI: there is no country as you mentioned where one has the freedom from all these gun regulations.
Oh, there are places where you can, at least practically speaking and maybe legally too, be free from our style of firearms laws, but they all seem to be the sorts of places no sane person with any choice in the matter would want to ... or dare to ... live.
