Likely will result in worse products as well (which is what happens when you remove competition).
LaTam is perfect example on how bad this "wide" protectionism is. There's a ton of economic papers about it.
If you really want protectionism, you could do something more similar to how South Korea did, by choosing specific sectors of economy you want to "protect", to create a "national industry".
Most protectionist industrial policies also exempt imports of machines and other supplies used in factories.
e.g. It makes no sense to put tariffs on machines used in a factory in the USA. AS that would make it more expensive for a factory to operate if they have to import a more expensive machine from Germany. "Buy a machine from the U.S", that would mean a more expensive machine likely, as it only exists because of tariffs.
That basically means you'll have factories on best case scenario, but your cars, your computers, phones, won't be exported.
It's great if you want to be self-sufficient pending a great war. The way things are going, it may be the only thing to justify such blatant self-sabotage, and hence necessary to start one.
