Here's another example: a market that has been completely dominated by China: consumer drones. Believe me when I say this, I hate DJI and while I have one, I refuse to use it because of all the security implications. How many European and US companies are competing with them? Quite a few actually but the big names off the top of my head are Parrot and Skydio. I own both a Parrot and a Skydio and the quality of both is amazing. Yet they are still barely keeping up with DJI and at 5x the cost despite the demand - DJI still holds 90% of the market share. I can justify the price because of my privacy concerns but that's 1/1000 people. For most people it's always going to be a trade-off between price and quality+privacy.
If you want to enforce all that through tariffs, just put 5000% tariffs so that the local manufacturing cost will be the same as the cheap import and you solved the problem. How many people will be willing to spend 100 bucks for a pair of socks? That's a different story. The soviet union attempted something similar for several decades while trying to copy western technology. Anyone that knows a bit of history can tell you how that ended. Spoilers: not a success story.
