IMHO, ANY form of infringement or registration is a big deal. Having a photo allows them, at any point and time in the future, to potentially lock in that configuration, force a reassessment if altered and even potentially revoking the privilege they so graciously granted you (vs. a right).It's not a big deal. Not everything is a conspiracy.
Call it fearmongering, but there where plenty of people trying to put it all down to bunk about 10rnd mags, AWB's, FRT's, braces, 80% frames/receivers, shipping sevice bans, red flag laws, etc.... and look where we are now.
The more you give, the more they'll try to demand.
None of it's truly about public safety... which is what gun laws/restriction are "supposed' to be for, right? So in that sense, the narrative they are trying to sell vs. the real motive for more power and control could certainly appear like a conspiracy.
