THe problem with this prediction is that there is an astronomical amount of money tied up in global trade. To stop that would be incredibly disruptive. Thats not to say it won't happen (history has plenty of examples. WWI is a recent one). However for the "end of shipping" to happen we need those vested interests to stop being interested in literal trillions of dollars worth of trade. I can see a few scenarios where…
As the US is largely self-sufficient in energy and will likely start becoming self-sufficient in a great many things, it needs the rest of the world less and less.
Those shipping lines, which mainly benefit the rest of the world, start to look like an expensive relic with each passing year.
All it takes for an end of shipping is for the US to stop protecting shipping lines which mainly benefit foreign governments.
