Meno: Please clarify what point you’re trying to convey. Are you asserting that if milk that has no hechshor whatsoever is being sold in the U.S., people who use Cholov Stam would have no problem buying it and drinking it and actually do so?
Because according to Rav Moshe’s heter for Cholov Stam, such milk is kosher to drink. So those relying on Rav Moshe’s heter for Cholov Stam should drink such non-hechsher milk in the U.S. just as they would drink OU-D milk in the U.S.
