You don't think US states compete with, undercut and stifle each other?
Second question: you think the USA has a strong federal government?
I mean that is actually an open question even in non-Trump years, not least when one side of the political aisle was famously dedicated to shrinking it down so small it could be "drowned in a bathtub", to quote one of its more famous assholes.

Compete with each other, yes.
But all US states take pride in Silicon Valley being American.
No EU project for its own "Silicon Valley" can succeed, because the French would insist on it being in France, Germans would insist on Germany, Dutch in the Netherlands, etc.
