(The US constitution originally required federal taxes to be apportioned for exactly that reason.)

Moreover, it's ignoring the context of the thread. The relevance is obviously that coercing someone to do something against their will and then saying they're still in charge because they're the ones doing it is a sham.
In the EU this appears to be classified into "exclusive", "shared" and "support" "competencies":
> the EU has competence to support, coordinate or supplement the actions of the Member States (article 6 TFEU) – in these areas, the EU may not adopt legally binding acts that require the Member States to harmonise their laws and regulations.
So for example, one of the areas in that category is industry.
The common trick to look out for in cases like that is that when they want to regulate something like "industry" they instead categorize the rules as something else, e.g. the US infamously regulates non-interstate non-commerce as "interstate commerce".
The Federal government using the withholding of funds to get the states to do what it wants is a well-documented phenomenon.
My previous comment should be taken in its entirety. The loss of sovereignty of individual countries is comprehensive across all domains and this is just one brick in the wall.
This is nothing new, this is what "European integration" means. I wanted to point out the very newspeak-esque use of the term "sovereignty" in Europe at the moment.
I would think the idea is to make services and ID documents more uniform across the union. I don’t see what the individual members state lose here? Apart from the cost of implementation. The individual EU citizen would seem to benefit from standardized documents accepted by all companies and governments, do you disagree?
