Yes, Tor is not the answer. I can think of a hypothetical technical solution to the problem, however. If everyone used an onion-routing protocol where everyone also acts as an exit node, you could create a situation where even meta-information would be unobtainable.

As it stands Tor is deliberately routing the majority of the traffic through a minority of the available exit nodes, they explain that they do that for performance reasons. Given that they are financed almost exclusively by the US government and some of the developers have very friendly relations with law enforcement to this day, it is at least plausible that there are other reasons at work. In some of the leaked NSA memos they even state that while they have not been able to fully compromise the tor network so far, at least the majority of their targets are using it. All of this is a clear indication to me, that TOR should be abandoned sooner rather than later.
