Hash rate is part of the 51% attack problem.
Which isn't a problem, so doesn't need to be fixed.
I think you may be underestimating the dangers of mining concentration.

You clearly haven't been paying attention in this thread, or you'd realize that my response was in reference to S4VV4S claiming that it isn't a problem for pools to have 51%, and then demanding that someone try and fix this problem.
If he doesn't believe that there is a problem, then there is no need for him to continue demanding that the protocol be "fixed" (why fix something that isn't broken?). If he feels that the protocol must be "fixed", then he should start admitting that there is a problem. Until he gets over his cognitive dissonance, and chooses one side of the debate or the other, any conversation on this topic with him is useless and unproductive. Every time you tell him that he has the power to vote with his hashpower, he states that he doesn't believe there is a problem that would require him to do so. Then in the same post he talks about how the problem needs to be "fixed".
