I did not say „special people“. The confidentiality privilege applies to the keepers of the information about identity, not to the people who own the identity - that could be anyone. If some government wants to control what you say online, they will make sure you do not have any anonymity at all, like China does with Uigurs by forcing them to use devices with pre-installed tracking software. Many countries do not have technical capabilities to do so, but this also means that main beneficiaries of anonymity there are radical political and criminal groups rather than ordinary people, which may not even have good access to the Internet.
