Interesting questions.  I support drivers ed in schools.  Gun safety ed is certainly needed.  I hate to keep piling up things the schools have to teach, but obviously guns are killers and the US has the highest rate of gun violence of OECD countries, and Alaska the highest (or close) of any state, so it is certainly a crisis here, and now.  After all, toddlers killed more Americans than terrorists in 2015.
Licensing - I don't have enough information to answer that question and I'd need to think about it.  I certainly would not support it being free.  It costs to get a driver's license, in part because it requires state employees and computers, etc. I don't want to subsidize gun owners.  BTW I am a gun owner, but the ignorance of people playing with loaded guns, and leaving loaded guns laying around, and the fallacy that owning a gun makes one safer, I find infuriating.  A well-regulated militia is one thing.  What we have here is entirely another.
Thanks for the discussion.
