I’m not sure the “implosion is inevitable”, but this is an interesting approach:

Achieving Gun Control: Exploiting The NRAs Unavoidable Implosion

“…To effect legislative change it is necessary to reframe the debate into one where opposing sensible gun control measures becomes onerous to elected officials or those seeking office. And it can work. In a test case, with the legal support of the Brady Center, I was successful in reframing a gun debate in NC where a ‘concealed guns in restaurants/bars’ bill was moved out of being a gun rights issue into a business liability and business owner rights matter thus eroding support in the business community…”

And from the second link:

And Tennessee State Representative Curry Todd, the sponsor of that state’s ‘guns in restaurants/bars’ legislation, repeatedly stated during the legislative debate that no responsible gun owner would drink while in possession of his/her firearm. In October of last year he failed a roadside sobriety test, refused a breath test, and a loaded .38-caliber handgun was found in a holster between the driver seat and the center console. He was booked on both DUI and gun charges. Representative Todd was not only a licensed gun owner but was also ex-law enforcement and yet still violated the very principle he used to successfully argue for the legislation in that state (ref). His mug shot is in the following image, where he claimed he had only had two drinks.
