I've been thinking that as soon as we remove the fully resisting opponent, we take a step toward the no-touch throws like in this vid. So to argue for training with [an] (?) uke is in essence the same argument as saying why the need to touch them at all.
I don't think they're the same. My limited understanding is that no-touch stuff is about psychological leading and positioning, which I think is a part of Aikido. I think it can very easily lead to preprogramming instead of organic interaction, but that simply doing them doesn't preclude that organic interaction.
