I'll concede that to you...I (respectfully) disagree. Wouldn't you say that SB292 (as finally enacted) last year represented incrementalism?
My biggest problem with your plan is the idea of adding a tax to end legislation does not work and will never work, the only then it does is start another never ending tax...Perhaps I am just too jaded on politics, but I don't see the feasibility of a legislative frontal assault on NFA 34/68. Post-Heller, there may be a legal attack, but on the legislative side, I think we are left with guerrilla tactics.
You wanna start making assaults against the NFA BS, then start by bringing about the end of the '86 Legislation and work backwards in chronological order repealing/overriding the different bans...
