Do you believe people should be able to traverse the internet anonymously?

Why should you be able to traverse the internet anonymously? You cannot traverse real life society with the same expectations. Majority of the people traversing anonymously are doing so because they are routine troublemakers and do not want to bare consequences for their malicious actions. The ones fighting for this complete anonymity but not doing crime are naively just sweeping for bad actors.

You can't. Even if you haven't registered or logged in, companies like Facebook have identified you and track you everywhere you go.

Yes. At least to read.
