We'll drop the other matters because I don't see them as serving any point to discuss further and I doubt you do either

I basically have two first principles on guns:

• Tyranny is never more than one bad generation away form happening anywhere, either because of being weak to invasion or careless in who we elect, so it is advantageous to have a population with access to so much weaponry with so little cataloging by individual it can't realistically be confiscated.

• People have a right to protect themselves in any fashion which can't be demonstrated to be considerably more likely to hurt non-aggressors then protect from aggressors. This right can only be lost if it can be proven beyond reasonable doubt that you represent a significantly increased risk of danger with one, because everyone does have a right to defend themselves.

These two mostly match up in the current scheme of things. On the first, I like to remind people that we tend to lose as many soldiers to training accidents as in war, there are clearly a certain number of casualties we're willing to accept to minimize the risk of the loss of more lives or those lives living under a tyrannical yoke. So even if I thought banning all guns would not only make them disappear but eliminate every murder/accident done by them, rather than simply change the means to knife etc, I would still oppose restrictions because our loss rate to violence in this country is inside acceptable values to me. I don't view that as callous or draconian, just common sense recognition that Utopia is a long way off and that standing down to pacifist peace is premature when most of the world's people live in dictatorships and a lot of the remainder live in Democracy? rather than Democracy. Mexico is better than average then most official democracies, in terms of pop, even excluding the total jokes where Glorious Leader wins 99% of the vote, and obviously Mexico isn't a place where one can feel safe from tyranny.

So from my perspective, the situation has to be approached under the assumption one can not prevent reasonably easy access to weapons by all, because you get that if you have reasonably easy access by many which also can't be tracked in any fashion that would let State Security or our Foreign Liberators from showing up on your doorstep requesting you turn over your weapons and them having an accurate list of how many and what.

Can you do gun safety from this standpoint? Sure, I've discussed some methods before and I do it from the standpoint of statistics and common sense. Part of this comes from the increased safety and security and confidence imparted through basic instruction. Looking like a victim is a good way to become one, predators seek weakness. And as you've mentioned, much of this revolves around deterring the least determined criminals, that's going to apply to situations where they think there is a reasonably high probability a potential victim may be armed and dangerous. If I'm a mugger I'm going to be a lot more deterred by knowing 1 in 10 people walk around with a concealed weapon then by having to find a friend to buy a gun and lose it.

So my safety and control method is easy, I'm open to any option which encourages more people to seek training with weapons. Emphasis there on encourage, not make. I wouldn't try to control who can buy a gun at all, I'd just establish who can't own a gun and for how long. Armed robbery? 20 years of no guns, murder? Permanent, stealing a car, a few years or not at all. And you setup an anonymous tipline with a big reward and a big penalty for carrying a gun or having one stored in your residence (yours or not). I wouldn't even bother trying to control sales, it simply serves no practical purpose and wastes time and money. Dump those funds into a tipline reward account and safety training courses. If getting caught with a gun is going to get you thrown back in jail for a decade and you know there's a very real chance every time you try to commit a crime on a person they might shoot you dead its a much bigger deterrent then anything I've seen the left suggest, and it also doesn't even vaguely impact our own rights, which all your suggestions do in my opinion.
