Yes, but this is only one of the excuses US Security Agencies use to target traffic, and there are enough other excuses that almost all traffic is eligible for surveillance. Legal approaches such as those taken by the EFF and ACLU have a lot of value, but I don't think a legal approach of trying to keep your traffic legally un-tappable is going to work. It's clear that the NSA et al are above the law and unconcerned with your rights, so until that is fixed, it's too easy to fall into a "grey" area where they have an excuse to monitor your traffic. Fundamentally this is an approach that tries to make it so the NSA won't surveil your traffic, which places an unearned amount of trust in the NSA. I think a better approach makes it so that they can't surveil your traffic--and for this there are only technical solutions. Part of this is making sure that the NSA can't spy on who you are talking to, and every solution I know of to that bouncing traffic across multiple servers. I would be very skeptical of such a system that didn't bounce traffic overseas.
