I haven't finished reading this yet, but I don't think the author is saying that the Landauer limit for erasure is wrong. They're saying that there are other limits in computing beyond erasure. I think this makes sense; although reversible computing should be possible at zero temperature and infinite precision, realistic computers need some way to remove entropy that accumulates during the computation. So I don't think their claim is in tension with any of the papers that you cite.
