Thanks. The above points you raise are crucial ones. A counter argument is that certain types of guns have no real purpose other than as collectors' items or as weapons used to kill people. So what would be given up by a ban on these weapons is itself of very little value to society. (Of course this is after we have disposed with the argument that these weapons are needed to defend society against the government. That's something I think we already agree on.)
Collectors items, fine. But guns that are used to kill people are also used to defend oneself against people using said guns to kill you. So removing a law abiding individual's right to defend himself from someone wishing to cause him harm is not the solution.
The second point is also crucial, and I think it is made especially so in light of the Heller decision. We have a right to defend ourselves in our homes! My argument would be that there are types of firearms, for which a ban on sales is not being considered, that are readily available and that are reasonably adequate for home defense.
No argument here. But you can't expect someone to defend their home with a bolt action rifle with 5 bullet capacity when he is facing a home invasion of 4 thugs with an AR15 or even a pistol. And until you have a solution for this, you will never get the support of the people you are attempting to disarm here.
