We literally grant 20 year monopolies on technologies to their inventors and have for centuries and it's fine. The entire economy runs on chips made by like, 3 foundries using lithography machines made by 1 company. I think you are overstating the necessity.

Autarky would be a national security disaster manifested. You can't be a modern prosperous society and not rely on either trade nor private enterprise.
I totally agree, hence my previous comment
