There is in fact some discussion, but half-hearted. There doesn't seem to be the political will to actually do it.

Why? The response to that question is inevitably political (because it's a political question). My personal opinion: because the EU has swallowed neoliberal ideological kool-aid hook, line and sinker, and will blindy follow it even if it leads to self-harm (which is funny, because the US, which is the main source of that ideology, has a much more pragmatic approach and will happily ignore it when it's not beneficial: see all the bans going on with China, etc.)

Unpopular opinion here, I guess, but that's my take on it.
