Can't do anything about the $200 without Congress changing or repealing the 1934 NFA. However, as he mentioned in the video, the 1986 FOPA that closed the machingun registry gives the ATF director authority to temporarily reopen it for amnesties, which would allow everyone to pay $200 to register a brand-new auto sear. And if enough people did, that could turn the recent "in common usage" Supreme Court precedent against the NFA and get rid of machine gun restrictions.
