I think you're absolutely correct that Google Glass users taking lots of unwanted and unnoticed pictures wasn't a big issue. I do think that most people won't understand those nuances and just don't like having a camera pointed at them all the time. It will be interesting to see if social norms catch up to the current law that people in public can be photographed/recorded freely. From a product standpoint I'd like to see Google launch a camera free version, get people used to it and then put a camera on it.
