Rather, it entrenches the power to the bland, indistinct body of politics as a whole, which expresses itself through numerous voting choices that are hard to distinguish from one another and are more less the same ideology, which can get large numbers of votes through choices that are only ostensibly distinct. It suppresses votes for choices that stand out from that group.

I don't think that is even necessary because the current voting systems already eliminate the fringes. For instance in many countries there is effectively a persistent two- or three-party system, even though other parties make an appearance.
