I am from Brazil and it is not unusual for companies to operate only within certain states because of this. Even though Brazil is a single country with a single language and mostly federal rules about things, there is still enough variance of laws from one state to another to cause problems.
Then you hear about Canada which has tariffs between its own provinces, but not to the US. Meaning some products are cheaper across the US border than across a province border. Figuring out how much to pay in taxes alone can be a blocker...
This is not an EU-only problem, any large single market will have friction in its internal divisions. It tends to be worse in the EU because the countries have a lot more sovereignty though (enforcement agencies tend to be local, not federal for example).
Canada doesn't have, and should not have, the level of ambitions the EU should have. We're talking about EU 450 million people (500+ million if the UK rejoins at some point) vs Canada 35 million.
The EU should go toe to toe with the US and China. The EU is utterly dominated by US software companies and by Chinese green tech companies (batteries, solar panels, EVs).
No, that is actually one of the points, I'm glad someone noticed it.
I, too, want to have my cake and eat it, too. This is a contradiction that can't easily be resolved.
I'd want Romanian sovereignty AND the convenience of big companies with lots of economic power. I guess, to your direct comment, yeah, I'd be happy enough with a few European "champions" out of hundreds being Romanian.
Personally, I lean more towards EU federalism so this cognitive dissonance is probably 30-70 towards big companies, because I think otherwise the EU will be crushed by outsiders.
Anyway, your name sounds Dutch. Please bring Albert Heijn to Germany. I'm not even sure why, but it's my favorite supermarket I've been to so far.
And Auchan has stores in Spain (Alcampo).
I'm not saying that the boundary is a 20km high wall of fire nothing can go through.
I'm saying that:
1. the direction is mostly big countries -> smaller countries, and very rarely big countries -> other big countries or even rarer, smaller countries -> big countries.
2. 20+ years after the EU has started, the level of high level integration is still pitiful.
If I go into the Carrefour in Sallanches (FR) then I will buy a completely different set of products to those that I would buy in the Carrefour in Aosta (IT), the two are 80km apart, I have shopped in both multiple times.
I don't think the supermarket example really maps across to the subject of the linked article.
=> short term gain, free profits for eg FR or DE companies being allowed to devour other smaller countrie's markets
=> big country corpos get used to "almost free lunch"
=> big EU corpos fail to innovated and become uncompetitive globally
=> US ans CN corpos try instead to come with their increased efficiency and innovation at the EU market
=> EU freaks out and throws random restrictions and fines and regulations
=> only the most aggressive and ruthless CN (Temu etc) and US companies get through
=> they mostly rape the s out of EU markets
=> EU tries to protect its markets but its institutions have been regulatorly captured
=> [dark spiral goes on and on...]
