And governments are truly powerless against this new technology.
I'm not sure that is true. Does that make me a troll? Of course it does! As long as the price of DRK is generally going up nothing negative can be said about the coin without people freaking out. Also I think DRK is overdue for a correction so I'm spreading FUD too.
I also forgot to add that I'm just mad that I didn't get in earlier which is why I'm spreading this FUD. Makes perfect sense.
Until you or someone else comes up with a credible potential spanner in the works, I'm pretty much doing the opposite of freaking out.

I have yet to hear one such sensible argument.
The NSA and the foreign equivalents have the internet backbones and routers thoroughly tapped with backdoor chips.
The US Gov could for example as part of the fake War on Terror (elevated by another manufactured 9/11 perhaps) have an excuse that the sheeple would buy for doing the same with all consumer level internet connectivity devices (backdoor chips in all home broadband routers etc.). Can't have anonymous money transfers with all the fake western backed terrorists roaming the planet now can we? They could filter all protocols they don't like including Cryptocurrencies/VPN/Tor/I2P etc. Not a too unlikely a scenario considering that US and other western citizens have been stripped of fundamental rights such as habeus corpus due to the fake war on on terror: See Bills: Patriot Act 1/2 + NDAA.
Besides a dystopian situation such as the one I described there is nothing that can stop the advancement of anon cryptos.
