I appreciate your patience with my typing. My phone is not the best platform, but using the Selectric is impractical here.
I can only respond that my Constitutional right to bear arms implies a duty, but not a need. A right that is contingent on some need is not a right at all.
And for that purpose, it should not matter if the firearm is purchased, acquired, or made by me. Same thing, same right. The government may have to show why it needs to have a record of my possession. Currently in the US, a purchased firearm implies a record of ownership, and we are generally prohibited form purchasing a firearm for someone else except as a gift, and that's a bit grey if you read those laws plainly.
To consider the nature of the Constitutional rights we enjoy, why are you writing here? Do you need to express your thoughts, so compelling? I neither deny nor question your right to do so, bound only by the limitations of the forum and media. And even then, I would defend your right to free speech, then bound only by the limitations of civil harm (yelling 'fire!' in a crowded theater for example).
Licensing implies a governmental control over the action. I reject that, but tolerate the current situation. But to go off on another tangent, it was not long ago a tenet that if you did not have the right to make a thing, you did not actually have the right to own it. Being forced to obtain that thing only through the approved means is not a right to possess it, but rather a privilege that could be withdrawn. Not a right then.
We have the right, in this nation, to possess firearms, limited only by common-sense restrictions, and sadly in some jurisdictions by unreasonable and arguably unconstitutional restrictions. Those would need to be addressed by any citizens affected thus.
My base point here, I have the right to possess a firearm, and should not be forced to show a need, no matter how I acquire it.
Parting comment - this, now, only an important issue because it has become practical for a sufficiently motivated individual to actually make, fabricate, useable firearms. It took more effort and knowledge previously. And so we find that a right that was difficult to exercise can, when it becomes accessible to more citizens, than is as danger to those would restrict it. They are still wrong. A corollary, public court records were commonly freely available to anyone who sought them out, with reasonable restrictions. Modern court systems, using digital means, suddenly found that the unwashed were pawing through online records. Aghast, many such court systems erected new restrictions to access, disguised as fees, licensing, etc., intending to keep these records private despite laws prohibiting that. A regular fight nowadays. Similar issues. Similar problems.
