Conversely that naval traffic MUST be done on US-built ships with crews that no how to man them which is a national security thing. I don’t see how allowing foreign built ships ie foreign crews helps with that aspect. Consider that we’re trying to onshore industrial things precisely for that purpose now in preparation for a potential war with China over Taiwan.

I also challenge that it’s also impossibly expensive because it that were the case things in Puerto Rico would cost much more whereas they’re a little bit cheaper than Miami.

That’s not to say that the Jones act should have reforms applied, particularly with respect to helping Puerto Rico compete more fairly, but I don’t think it’s clearly one of those totally evil regulations that’s hampering US creativity and ingenuity from flourishing.
