That's not the actual history of these types of of actions. Look at the 1982 IBM / Japan theft case (https://www.nytimes.com/1983/02/09/business/hitachi-guilty-i...).
IBM was aggressively protecting its mainframe market in the 80s so it would have a blossoming and prosperous future.
Even if we are to accept your premise AND all your arguments, it's still a bad idea as it actually led to a stagnation of technology.
There's plenty more historical examples of this. It doesn't work.
Take the Japanese automobile quota system for example (https://www.google.com/amp/s/www.csmonitor.com/layout/set/am...). This tried to protect encroachment of Japanese cars into the American market.
Not by increasing the quality but by suspecting the Japanese of stealing American know-how. A covetous and revanchist policy.
This only led to them internationalizing their markets more and working around the US in their supply chain. The US locked itself out of the market, became insular with its cars, stagnated and lost its place in the international market.
And now everyone is doing lean manufacturing which is from Toyota. Turns out they were just making better stuff and our policymakers were too racist to acknowledge the possibilities just like we thought Afghanistan was going to be easy, or Russia thought they'd easily defeat Japan.
The haughty racial superiority complex is alive and well.
