A secure messaging system could have other benefits. The problem of spam is increased because it costs nothing to send email. A short message service that you needed to pay a few bitcoins for to send a message might revolutionise sms or email for those who are tired of sorting viagra and nigerian scam emails all day long.
Great point…I’ve heard something called hashcash does this for email. But with bitcoin, one can additionally prioritize messages: .g. the message with 10 BTC attached to it is probably more important than the message with .01 BTC attached.
