Someone on /r/shadowrun came up with the idea that maybe the reason monocles are restricted is because mages can use a monocle to see AR/VR and the real world to cast spells at the same time. So its kind of a way to control hacker mages, or just stick it to them. I could see propaganda to make that law. "Not only can mages set you on fire by just looking at you, they can also hack in to your commlink and steal all your bank account information. We need to do something about the widespread abuse of awaken hackers."
