OK, thanks, I get your point now.

On the other hand, I get the impression that Soylent is mainly intended to substitute junk food, rather than gourmet meals, so, hoping this rope doesn't snap if I pull it this far... Are blow-up dolls better or worse than low-end prostitutes? Meh. What is it to me? De gustibus non est disputandum. Let the market decide! (Of course we don't know the market will locate the optimal result, because imperfect information/externalities/irrationality/etc., but if anything I'd expect these to favour the junk food.)
