You'll never obtain universal agreement for a mine, because there will always be a contingent for whom the correct number of mines is zero. They'll never put it that way, of course. But the decision process they exhibit is "new mine? no", and the consequence of realizing those preferences would be zero new mines.

Fortunately, checking to make sure the entire Internet does not have a website disagreeing with the decision to start a mine, is not part of the process by which mining is started.
