I would say the same thing about the opposite. What do you think people are going to do, take time out of their way to go turn in thousands of dollars worth of guns and ammo for nothing in return? Do you think cops are going to go door-to-door seizing guns and that nobody is going to ever fight back despite being fed the fear of the government barging in and taking citizen's guns by force for their entire life?
I don't believe gun control is effective unless nearly the entire population is accepting it willfully, and if people wanted to do it willfully it would be easy to gain a large majority of votes for that cause. But even the democratic party in some of the densest cities struggle to gain a simple majority from voters on the issue.
I also don't think the government has the power to take peoples guns by force even if they wanted, it would collapse the US if even a tiny portion of people fought back and defeat the entire purpose of trying. Would the US military lose battles against citizens? No, there wouldn't even be very many. But they still wouldn't win the war when some random hillbilly takes a few pot shots at a sub station from 2 miles out and takes down the power for potentially millions of people and all the work and value they produce. Factories don't work without power, essential munitions don't get produced if they can't secure material inputs from across the nation or the world, and if financial institutions takes a dive in response to destruction and chaos there goes US trade power. And you can bet your ass that all the countries the US has been taking a dump on for nearly the last century are going to take advantage of a weakened US.
