No matter what you think of this ban, the court is obviously not the right place to solve it. It is completely unsurprising that this is a unanimous decision because foreign trade is one of the few powers expressly given to the federal government in the constitution:

>[The Congress shall have Power . . . ] To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;[0]

(The actual law may not have relied exclusively on the Commerce Clause, you would have to read it to find out. But from a high level there is nothing stopping congress from regulating any instance foreign trade.)
