The problem is that those 27 sets of laws basically still exist. Regulation is certainly not the only reason. Fragmentation is another massive problem.
There's the EU-Inc initiative that the EU has basically made pointless (by wanting to introduce 27 new standards, not one, just making things more complex).
There are no 27 sets of laws to do business in Europe. It's not perfect, but it's a SINGLE MARKET, if you comply to the EU regulation you are allowed to sell everywhere.
It does however not absolve you from additional local market demands to be competitive, i.e. local language support, service infrastructure, etc.
For example: Miele is one of the largest washing machine manufacturers in Europe. They have their front panel translated to local languages for most of its markets. You can sell a washing machine with a English front panel, but you won't be able to compete in e.g. the German/Italian/French market
I heard they make quality products that last 20 years and don't use WiFi, too. Maybe they should try exporting to America.
If true, it's indicative of some American vs European ideology. American tech bro soyjaks keep screaming criticisms about things like GDPR preventing remote-brickable wifi washing machines, and European bases nordic mans are like "bro those things are crap, why would I want them"?

Note that I'm not arguing for zero regulation.
