The problem is that this is this hard for you to understand.
Not quite. I am not the one who is having difficulty here. You've already agreed that an 8 year old can be taught safe and responsible gun usage. However, you've made a distinction that it is not acceptable for one to own the item they will use.
I asked for a practical reason to differentiate, in law, between ownership by adult and usage by child, and both ownership and usage by child if the usage is equal, to single out ownership. Your response lacked such a difference, it showed a complete misunderstanding of the word "practical" itself.
To further explain why I asked for this, my philosophy is very much along the lines of: "You do not need a reason for something to be legal. You need a reason to make it illegal". That is, "there is no reason(read: that I can think of) for x" is a wholly unimpressive argument when talking about liberty, at least to me and those who think like me.
Lastly, if you can show a reason for rejecting the child's ownership of the gun, while accepting the same actions taking place regardless of the child owning the gun(the training of proper, safe, and responsible usage of said gun), I will explain how and why ownership can be beneficial.
Cool. So, in fact, this odd mindset of yours about children and guns seems to come from how your parents raised you.
It is not my mindset on this that is odd
But yes, I was raised in a way that allowed me ownership of possibly dangerous items so long as I exhibited responsibility in doing so.
The fact that guns don't get used that much
How, as I asked several times, do you determine this?
while there are always people driving their cars all the time, and I know that most people in most places drive to and from work around 5 days a week, along with driving many other places
I did not ask how you determine car usage. Cars, being relatively large objects all around, are somewhat easy to notice.
