I understand this is the point of EU policy, but if you are a country with a history and a future, given how it has gone for everyone else, why would you give that up?
The examples below are from giving up national accountability for their own policies to "harmonized" EU regulations:
- Greece's economic collapse as the consequence of predatory ECB lending
- Spain's economic collapse from related causes
- Germany's failure to manage its national energy needs due to EU "green" policies made it subject to Russian energy dependency. The US had to literally rescue Germany from itself by blowing up Nordstream
- Sweden's no-go zones
- Italy's costal humanitarian crisis'
- Ireland's collapse of their "tiger" economy and yet another serious migrant crisis
- In France, French people are treated as occupiers in their own cities, e.g. Bataclan, Hedbo, etc.
- general anti-family and anti-natalist policies have stopped replacement level birthrates in all EU countries.
