The point is if it got Sybil attacked, we have to improve how we validate witnesses as actually being individual entities. To launch as successful Sybil attack (to date), apparently you do.
No, I don't think "everybody" but maybe some type of advanced reputation system for witnesses that have some kind mechanism for determining the likelihood that the witnesses are individually controlled or part of a sybil attempt.
I've been thinking about some of this stuff for a while:

I don't know if 1t1v or max votes of 1 is the answer, but I hope something is better than what we have now.
