The argument was whether they could scale, and they don't seem to be able to beyond a certain point (and even then only in fields of dubious value like banking). Whether or not scaling is a good thing or not is an entirely different thing.

I don't think it's an issue that they can scale, I see no reason they could not, I think it's because they don't have the appetite to do so.

There is nothing intrinsically limiting about the format of a coop that would prevent it from being as big as needed, IMO.
