Earlier quoted context omitted.
Speakeasy bars in faraday cages that pulse you with an EMP at the door would be cool too. We could also just stop non consensual surveillance of everyone and everything . I prefer that option.
EMP are easily repelled with faraday cages
I'm also joking, but only partially. It could be a fun gimmick. Check all your electronics in at the door, go through the doorway with an EMP zapper, and then enjoy a distraction free camera free evening. You get banned if you get caught sneaking in electronics and you might wreck your expensive phone, so why risk it.
