I don't think you understood my point. This "disadvantage" applies the exact same way to starrups every other non-US country, it's not something specific to the EU so it makes no sense to posit it as an EU thing.

This was my main question, and it looks like the answer is indeed no.
Still, the existence of the EU is (to bring peace by) lowering, mostly economic, barriers that traditionally exist between countries.
And the comparison in this threat was "between EU and US" (in europe Thing is hard... in Europe you cannot... etc). When people use "The EU" or "Europe" in this sense, they consider it as a "Single thing". Europe, or the EU, has a great disadvantage for startups over the US. You say that is because Europe is not a "thing" like a country is. I say, that is because Europe seen as a "thing" lacks some critical infrastructure that "the thing called US" has - or even "the thing Brazil" or "China" do have, internally.
