I'm not so sure. There's a type of person who would deem the US Government having a privileged role in coin governance as a legitimacy-reducing factor for that coin, and that type of person is over-represented in crypto circles. Also there's a possibility that whatever coins decide to comply end up spending their reserves on humans-in-the-loop to ensure compliance, thereby giving an advantage to the noncompliant coins. Something analogous to this happened where I'm from: We voted to legalize recreational cannabis, but most people still use the black market because regulatory burdens put the legal shops at too great of a disadvantage to be competitive.
