That's a really interesting problem. 1. Say i care about privacy. I decide that all the help i give people over the internet, would be composed of a plain text teaser ,and an encrypted content. That's easy to imagine doing so in private messages , and even in small groups. Maybe even using some technical trick this could work on publicly posted information(or at least slow the rate/chance of wiretapping). And in those cases i only reply to messages sent securely. If enough people do this , soon enough , there will be plenty of encryption. 2. Make it a habit to embed an encrypted background channel in many apps that always transmits, that need comes be , can be used to transmit info. "Hey it's just a cool app man". If enough such apps spread, suddenly everyone encrypts. ' 3. Same applies regarding to anonymity.
