I think this kind of dual relationship can only hold until the two come into conflict for a large group of people. There's no issue (except philosophically) if food is a commodity that costs 1 penny per lifetime to eat.

It's only when many people face being deprived of their right to eat due to its status as a commodity. That's when you see revolution, insurrection, mob violence, all the rest. Housing isn't there yet certainly, but who knows how far off it might be.
