Bitcoin doesn't exactly have an efficient way to measure "consensus" and further, there's a major difference between what bitcoin users might think versus a consensus by miners, the vote of which is significantly concentrated the hands of very few relative to the number of bitcoin users as a whole. Plus, the frequent splits off the main bitcoin chain are instances where there have been major disagreements concerning the "consensus" about the proper protocols bitcoin should use. All this is a long way of saying that there's no credible "consensus" about bitcoin. There's a status quo which, for reasons that have nothing to do with consensus, is very difficult to change.
