Who is checking for that? Can you give me an example of any public authority within the EU that has the operational excellence to even understand how BigTech is collecting and handling data? For Germany I only see Ulrich Kelber who certainly does not have the competence to even understand how BigTech is doing their things.
Instead of developing operational excellence in their prosecution authorities to be able to track down and punish bad actors, they install regulations for everyone and try to simulate competence harming their own economy.
Not all crimes are preventable, which doesn't mean the laws aren't enforceable. Example: even though murder is illegal, people still commit murder, but they are rightfully punished for it, as the law mandates.

Do you have any proof that tech regulation is detrimental to the economy?
