Decentralization is of great technical benefit for technical security. It does not provide political security. Only legitimacy can produce true political security. And to have sustained security you need more than technical security. Silk Road had technical security on the foundation of Tor and because it was not legitimate it was politically attacked, sabotaged, and eventually the technical security was breached.

The same process will always happen until developers realize legitimacy is what can protect a platform from political attack. This means a platform cannot exist merely to help people avoid regulation or accountability.
