I agree to an extent. If France decided to implement these laws in their own country, 30 something other countries could shrug and do their own thing, while the French could attempt to fight it on a local or regional level. While the EU has enabled plenty of good, it's also the perfect platform to implement less good policies such as this in the interest of corporations or rightsholders on an intranational level in a way that wasn't possible before. It's also much harder to be heard as a citizen on the EU-level. I'm not sure what the solution should be, since overall I support the EU.
It's not like there's a national place where you can set up shop and protest or strike. It happens on a local or regional level just because of how geography and people work. If the national government doesn't give a shit either way, then I'm not sure what I can realistically suggest here, but it's irrelevant to the point I was making.
