Some privacy can be achieved by using Tor, but it is far from the fact that there are those who cannot find you even then, only if they want to.
When you say "attack on privacy", I ask you, do you still think there is privacy in the online world?
Of course there is. There is a huge difference between the privacy I have on this forum when accessing it through Tor and with a proton.me email address when I registered, and having to use a digital identity to access the internet, where each and every one of my steps will be monitored instantly.
It's the same garbage argument I've heard for accepting CBDCs. If you have no privacy when paying with VISA or Mastercard, what difference does it make if you use a CBDC? Well, there's an essential difference between the central bank having direct access to each of my expenses in real time and needing a court order to obtain them.
