I regard EA as a means to operationalise an already chosen ethical foundation - and Yudkowsky's article as explaining how to do that while still being human. I don't find 'grounding ethics' to be a particularly fruitful thing to attempt, and having looked at efforts to do so that clearly involved far more intellectual investment than I've put into it, the obvious holes therein suggest there are better things for me to spend my thinking time on.
