If I'm not so special, then why do my mundane activities need to be recorded? What benifit does it serve? Certainly not mine; the activities being recording are so unexceptional the only people to gain by having a recording of them are my loved ones who want a momento of the event or people looking for dirt on me. If I don't know you, but you are sending video of me into some cloud service, then no good can possibly come to me as a result. The most likely outcome is that nothing will come of it. But that is also the best case. The less likely cases are that I could loose my job, or be convicted of some bullshit crime.
I can appreciate the argument that you shouldn't do things in public that you don't want people to know. However the areas that are considered a "public space" has been expanding conciderably to the point where your personal home is the only real private space. But people aren't solitary creatures. They need to be able to congregate with others like them without having their activities scrutinized by the entire world, just by the community that they are interacting with. We need freedom to not spend our lives living like a PR representative on the stage every hour that we are outside of our homes.
