> Entity formation time; time and capital required to hire the first N employees; number, cost and time of licensing required before first sale can be made. Each are higher in Europe.

Which Europe? All of those can be done online with minimal effort or upfront investment in many EU countries. Do you mean Belarus?

> Combine that with the multiple languages and regulators which inhibits scale and you get the present situation.

This is true, because the EU is composed of 20+ different countries, each with different languages, cultures, histories, priorities. It's impossible to remove that boundary.

Each of them can be done online in most countries. All, very few. I think only Estonia comes to mind. (At least one form in that process requires visiting a notary in most of Western Europe.)

The cost of terminating an employee is also a unique risk that European firms have to capitalise for which American start-ups do not. Again, I understand why one would choose this stability. But it comes with a cost.

> It's impossible to remove that boundary

It's absolutely possible by mandating a lingua franca. But it would cause irreparable damage to those cultures, which is why the EU--sensibly, in my opinoin--has chosen to preserve them. But this is a choice and it comes with costs.

Spain still has not succededed after triying for centuries. Italy has "dialects" [1]. I'm not sure about the local detaild of the other countries.

[1] A dialect is a language without a flag or a float.
