The missing piece, is that film was expensive, and few carried cameras around with them. Unless you were on vacation, or going to a memorable event, it was rare for a person to have a camera on them in the 60s. They didn't easily fit in pocket. And rarer still for someone to spend a few bucks taking photos of unimportant things. (Film and development costs both were not cheap in the 60s) Most people only had 15 or 20 shots in their cheap camera, and wanted to save them for the party or event. It's not like there were endless professional photographers wandering around.
