The NSA revelations shown that governments are doing mass surveillance for real and it is not just a nonsense conspiracy. Right now maybe only ver few might get affected by this. But if in the future the people in power use that information against you or your people you will regret it to exchange your privacy for convenience.

Alternatively if the people not in power have a revolution and murder all of us working in finance... well shucks I guess that could be something I'd regret.
Waving around arbitrary threats doesn't help if the people you're preaching to view them as low likelihood.
