Disagree that it does that. It gathers provably-accurate information about votes, that is all.

Consensus exists because the network does not fail, and I'm not sure there is actually a better way to gather information than just that. That consensus is not necessarily egalitarian, however. Various parties may influence it in highly unequal ways.

I suppose there are different, largely subjective, ways to define what it means to fail. If control is centralized, even in a de facto manner, then I personally consider that a failure because much more efficient and mature centrally-controlled systems exist, making such a system pointless. Others may disagree with my assessment. No one can dictate what someone else values.
