Dash is far, far more susceptible in that analogy. For Cryptonote coins i.e Monero, you need no external nodes to mix transactions/provide privacy/anonymity. With Dash, the government(s) can take control of the servers the masternodes are hosted on, threaten with jailtime for masternodes owners, etc etc.
We went through this stuff in quite some detail. The conclusion, correct me if I'm wrong, was that versus guv/TLA all coins are fucked, so any argument about that is obsolete.
Not equally though. While it may be possible to force users of any coin no matter how anon to reveal themselves through force or w/e, coins that utilize an external source to provide anonymity such as Dash are far, far more susceptible to such a thing, than coins that do not such as Monero or future Zerocash.
