I think that the point being made is that in a world with true equality, there is no bar, because each person's perspective is as valuable as any other's. The existence of a baseline necessarily requires choosing a perspective and enshrining that as an ideal to be aspired to, which is a power play on the part of the person setting the standard. There's nothing inherent about reality that requires that: the alternative is that you do your thing, I do mine, each of those things is as valuable as the other, and if our things conflict we work out our differences amongst ourselves (or if necessary, bring in a neutral third party to adjudicate that is mutually acceptable to both of us).
