What other private property does that city perceive they hold title to? Are they going to buyback your car? Your wife’s wedding ring? Your tools? Your computer? Your investments?
Since firearms are an inanimate object, how about a buyback program on those persons committing crime? If good cash awards were offered to turn in or locate bad guys... maybe that would have a reduction in crime. Imagine the horror of driving a culture that wants to stop criminals?
The problem is that it would work, and would be quickly followed by cries of racism or some other nonsensical BS.
I worked with a lady who immigrated to the US from Russia. They finally got the OK and at the airport they confiscated her grandmother’s wedding ring and pictures of her husband in the military because of state secrets.
I asked her if she could have appealed and she said that it meant starting the immigration process all over and they could have confiscated everything again.
This is where we’re headed - the property is the gubmints and it’s by their good graces you have use of it.
