The lack of freedom for Greece to manage its finances is because it's a member of the Euro, not the EU. That isn't really relevant to the UK.
And as far as I know, neither the Euro nor EU laws limited the Greeks' ability to prosecute their bankers. Is there a reason those are connected?
Same could be said for Ireland[1]. You might wanna take a closer look.
In the words of M. Thatcher: "He who controls interest rates in Europe, controls Europe."
