Well, i don't have much to say.

But i think you wouldn't want to be anonymous while dealing with country own data, (e.g - creating of bank account,  national identification numbers, House address and others...) .

In terms of internet, anonymous would be a little bit difficult because of gmail, KYC verifications and more,
Even if so many people has fall into creating multiple or fake gmail accounts, face verification has started coming into the picture.
