How does Tails(or Qubes, or etc) provide security in a real use case full time OS system? Say I log into Facebook, obviously I expect my identity to be exposed

  There are different things, for instance: - QubesOS provides security by isolating components. So if your browser VM is compromised, your password manager VM is not. That does not make you anonymous at all. - I don't know Tails, but I think that it is just not persistent. Which means that when you reboot, you know that there are no traces of your previous session (as opposed to a "normal" system that would keep cookies, for instance). Which may help you not being tracked. That does not necessarily make you anonymous: you may leak your IP. I would guess that another thing is that if you get some malware in your Tails session and reboot, then the malware is supposedly gone (could it infect the hardware, e.g. a USB webcam? Not sure). There is no "one" security, it depends a lot on what you need (i.e. your thread model), and many tools provide many different features.
