It's a sad reminder of the optimism for the power of the internet we had in the 90's. This sort of reality only becomes true if we all use cryptographic measures all the time perhaps.
I guess the issue there is that if the general population spends most of its time on platforms which discourage anonymity then it becomes that much more difficult to achieve anonymity when you do need it.
Cyberspace can only be independent so long as it is a place that "is not where bodies live". "Our identities have no bodies" isn't true if your online identity is associated with your real name and photograph. You can't have a world that "all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth" if "all" doesn't include people whose race, economic power, and station of birth hasn't been disclosed to you in advance.
