We can see the same situation play out with manufacturing capability.

The USA has recognised that it needs more manufacturing capability. But rather than just build that capability (which is what the Chinese state-planned economy would do, and did) it tries to incentivise private companies to build it. Which didn't work because the companies building domestic manufacturing face competition from Chinese imports. The investment money can get better returns chasing property deals or rent-seeking monopolies.

In the "we can do it back" case, it still takes a US private company a lot of time and money to distill their model off the Chinese model. There has to be a lot of profit for them to do that. That profit isn't really available - it's a competition with all the other models, and no monopoly rents. There's for sure a viable business there, but it's a "lifestyle business" not the 1000x growth business that VC's want.
