Of course these laws have low rates of compliance at first... but they kill the gun culture in a state. An illegal AR-15 stuck in a closet doesn't help the gun culture at all.
This is my problem with non-compliance versus stopping or overturning the law. Obviously you can't always win, and I would "non-comply" if it came down to it. But then "they" still win, because I'm either hiding the guns or maybe sneaking them into BFE the desert to shoot them once in a while. They wouldn't see the gun range.
At least not unless there was a giant "non-compliance event", where 100 other guys show up with their illegal guns. If it's just me though, and an unsympathetic cop shows up, call me yellow, but I'm not up for being the example and doing pokey time or else losing all my money in legal fees. I've got the gun in a closet, but the antis still win because I mostly can't use it.
I'd rather fight via the voting booth and NRA-ILA, and maybe talk to all the so-called gun guys, who when you ask them to sign a petition or vote, give you the, "It'll never happen" line. Then become outraged after the votes are counted.
