Also, this sort of unregulated drug importation plan rather consistently results in fake drugs and low performing drugs being supplied by any company that can get away with it.
The same thing happened a while back when Bernie Sanders was pushing a similar unregulated importation of cancer drugs, which had already prior to that had an entire batch of placebo drugs get through customs. Cory Booker pointed out this issue, but Sanders (and his stans) claimed Booker was just shilling for Big Pharma by...wanting to regulate Big Pharma.
