I'll have to correct you here, while i am sure you can find (as i found) real parmigiano or in general good cheese in the states (by paying a lot of money for it) the law allows for additives to be added to it.
In europe this is illegal, you cannot have additives in parmigiano (solid or grated), and if found normally the product is retired from the market.
In general the FDA in the US is much more liberal in favour of the industry, sacrificing quality and this apply to several products.
(For example i found out that in the US the minimum amount of chocolate that has to be present in a chocolate product is like 10% and in europe is 25% (if i am not wrong) and the amount of max sugar is also different.
Said this, you can eat all the cellulose you feel like eating, but I think it's wrong to 1) charge for it as if it was parmigiano and 2) sell it as an italian product.
ps regarding your humidity comment
"Alaska is one of the most humid states! In fact, Alaska reports an average RH of 77%, with the next highest state, Florida, reporting a 74% average. Despite Florida being hot and balmy, Alaska has high humidity levels because of its milder, lower temperatures."
