Do you want to live in a world where you need permission to take a picture? We do not live in a world where a minority of people carry cameras: almost every cell phone now has an integrated camera, and almost everyone has a cell phone (even in remote African villages, people have cell phones, often shared among the villagers). Tourists have been taking pictures in public places, without regard for the strangers in their camera's field of view, for decades.
There are already other classes of always-on video recorders that people generally accept: dashcams, security cameras, etc. There are a few complaints from people who do not think wearing a mask in public is an acceptable countermeasure, but for the most part people do not mind -- as long as the camera is not pointed into their home. Google Glass is hardly different; in fact, it records video less often.
No I don't want a world where ordinary citizens need permission to take a picture--but neither do I want to live in a world where a google or Facebook employee can find out in seconds where anyone in the world is or has been and what that person is or has been doing. Ubiquitous, always-on video devices that are always talking to a server, combined with facial recognition and other AI would allow this, and there seems to be no legal or cultural prohibition against it.
