I think the point is that laws alone mean nothing. As you note, Taiwan was more active than just having commissions and signing papers.
Airbus proves the EU can do this. It remains to be seen if they still have the ability to take constructive action, or if “add more bureaucracy” is the only tool remaining in the toolbox.
I’ve seen someone explaining why it’s not as easy with semiconductors: Airbus can spread several different factories for different components around the EU. For semiconductors that’s not as feasible. Thus countries would fight which one would have the semiconductors factory. I think it was more or less this argument, which seems to make sense.

And Boeing's rampant carelessness proves European laws can be beneficial. "Hurr durr, how about them European laws" is a low-effort comment that adds nothing to the discussions.
The argument that a slack regulatory environment is sufficient was disproven when the US government subsidized new fabs via the CHIPS Act (a new law!), and then went further and partially nationalized a failing Intel to prop it up.

*could.
Airbus has been grandfathered into the current legal situation. Today a future Airbus would not be able to even start collecting data for its initial Environmental Impact Study.
