As for domain specificity:
I don't know any Europeans who'd prefer to have American healthcare.
I don't know any European technology companies that hold a candle to the sheer breadth and depth of capabilities brought into the world by Google, Apple, Microsoft, Amazon, Nvidia, AMD, Intel, OpenAI, or Anthropic.
Yes, Mistral, Nokia, OVH, and SAP exist, but compared to the alternarives, they exist in the way the American healthcare system exists compared to its alternatives.
As for granularity:
Perhaps we want American style governance for building the tech, but then European style governance for running it?
