This is my only real problem with DASH that hasn't been refuted - the fact that it depends on PEOPLE running servers, not cryptography, to ensure privacy.
Actually, if you look here: http://178.254.18.153/~pub/Dash/Masternodes_Map.html you will see that most of the MNs are in Europe Asia and Russia. Actually, the distribution is great in the Northern Hemisphere, and could use a bit more in the Southern, yet still, very well distributed. And the fact that one needs over 90% of the network to hope to decipher any information that's well hidden with 8 rounds of DS, you can see there is no way any single government could possibly do it. Even North America + Europe + Australia isn't enough. I'd say there is very little hope for Governments to do this, ever.
It's just a matter of how much you want to mix.
Can you imagine the trouble the governments have to go through to access so many servers? They can't just do that, at least in the USA. They have to have a warrant. If they can't show they'll get more than a 1% chance of real information from a random mix/transaction (not even the transactions they're looking for) they won't even be allowed to try.
Also, unless the MN is malicious, and recording mixings, there would be nothing to find.
I feel like this wasn't read?
