I too think that the database is their real goal. It’s possible that they won’t use it for complete confiscation; rather, they may use it for selective confiscation—only going after “enemies”. For example, the bodyguards of Hollywood lefties won’t be hassled.
Of course a database is their main goal. They get that and the rest is history............
“This year will go down in history. For the first time, a civilized nation has full gun registration. Our streets will be safer, our police more efficient, and the world will follow our lead into the future!” ~Adolph Hitler, 1935
