For the record I believe I agree with you. However I view it as governments are the failure point in the issues you list, not markets. They have outright failed to address the negative externalities as they have been captured by private interests. In my opinion the entire financial system is captured and the regulations they tend to introduce are simply to allow the corrupt private entities further control.

One neat part of anonymous online prediction markets using unregulated digital currencies is how they exist outside this crony capitalist system.

It’s not markets to blame. It’s bad government!
