Is there any reason why rice and other gluten-free grains won't also become more costly?

Nope. If the basic price of the grain the rest of the humans eat goes up, guess what happens to the demand for the stuff the
special people eat.
There is going to be mass indignation when the average shopper picks up a little sack of flour that costs as much as ours does.
