You’re incorrect about history. Mercantilism not only restricted foreign trade, but restricted domestic industrial development by requiring the colonies to sell raw materials to Britain and buy finished goods from the Britain. Tariffs were a core pillar of the Lincoln Republican Party.
There’s been an isolationist wing in tech as long as I’ve been in it (early 2000s). I remember chatting with someone at Cisco/Juniper in the late aughts about Huawei ripping off their router designs down to the silk screening. Of course today Huawei makes their own state of the art routers with their own silicon, and some lower-end Cisco/Juniper gear is white boxed foreign equipment. And of course tech folks were complaining about immigration and outsourcing back in the early 2000s when Republicans were enthusiastically supporting both.
