I don't think collectivists in general think that individuals shouldn't be allowed to own guns, but that ownership can be well regulated, in the sense that gun owners should be required to show some level of knowledge and such before purchasing a firearm (that is, ownership can be licensed[0], as opposed to carrying). Further, its not at all clear to me that carrying permits have anything to do with the constitutional amendment. The discussion at the time and the amendment itself refer to national defense, both from external and internal threats to the nation, not "bring a gun with me to the store" (concealed/open carry), which I think is what makes many people uncomfortable. Many other countries have regulations of this form, that you have to purchase safety equipment and the government can audit you to ensure that you are safely storing your firearms. This gets people concerned about the government seizing your guns, but I don't think those concerns are realistic (assume the gov decides to do that one day, does having a national gun registry and your gun in a safe make things look any different than the police going door to door with a swat team and searching the house)? I don't think it does. [0]: Eventually. this would take a generation or two
