DAI is immensely exciting. Stablecoins like DAI are interesting experiments that could powerfully create new online economies.
Blockchains like Ethereum are currently far more transparent than the state-sponsor US monetary system. I hope to live in a society where economic experiments can be executed, new lessons learned, and transparency maintained. If stablecoins are persecuted, the need for cryptographic zero-knowledge proofs will allow these systems to continue with far less transparency.
As a different matter, how can society say "2008 bad", which resulted in little economic progress, and then threaten problem solvers from making new solutions? Innovation is a hedge against regulator lethargy.
