Another senseless death and an idea whose time has come.

21. We're unfortunately talking past each other.

Just a few very quick points:

One book, not matter how insightful you find its arguments, does not necessarily accurately or completely portray the current state of the law or politics about firearms.

Comparing emergency regulations like quarantines to prevent the spread of an infectious are not analogous to gun ownership for a multitude of reasons, no matter how seriously you or others view the problem.

I believe you would be well served to conduct further research on what restrictions and impositions a license requirement can and cannot legally impose upon a citizen, particularly when it impacts upon a constitutional right.

If a law or regulation is unconstitutional, it's totally irrelevant how effective it may be to achieve an ends, no matter how noble. There are a lot of potential solutions to many social problems that are nevertheless forbidden because of constitutional restraints.

Lastly, as I mentioned, the legal problems many of your suggestions would face are immaterial if you cannot muster both sufficient and determined popular support to make them law. Congress cannot even pass universal background checks which are likely constitutional and purportedly supported by an overall majority of citizens. Other than very basic background checks, most state level gun laws have actually relaxed gun ownership and carrying rules, both due to popular support and judicial order. All this even after the massacre of children at Sandy Hook.
