There are three types of people who seek strong anonymity: whistle blowers, criminals, and tech-nerd posers. For this reason any viable, strong anonymous comms solution is doomed to be misused 2/3 of the time.
But in reality there is not an equal distribution between these 3 groups. And there is a high probability that the user base is not as limited as in your pseudo factual simplification. (journalists come to mind for example etc. pp)
