Running out of rennet?! you mean in your stomach, or in manufacture? ;-) If the latter, then there are perfectly satisfactory hard cheeses in the US wherever I've gone recently, which includes at least ten states. Some of it is imported from Europe if that makes a difference ;-) but there are also local producers doing a great job IMHO. This seems to have come about over the past five years along with an interest in red wines and organic produce. Meijer may not be Carrefour, but there's heaps of really healthy natural produce whenever I go in.
But then I suppose you know this very well and are simply seizing the opportunity to poke a stick? ;-)
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
