The first question about Chesterton fences is: why is it there?
My first year of running a simple business in Germany was unbelievably confusing. My only saving grace was that none of those laws are enforced. GDPR is a good example.
Europe/EU is not Germany… and Germany is infamous for it's dumb redtape and being stuck in "their ways" (if it works then it works then there is no need to change that" seems to be a proverb there, inni't?)
Besides - in majority of the countries you have to navigate the laws… either yourself or you get an expert/lawyer that does that for you o_O
