The problem is enforcement. The EU system doesn't work because it's not properly enforced. Spanish fishing fleets would regularly fish in British waters and Britain wasn't able to stop them, despite the rules. This is a general pattern. The EU has many rules that are supposed to be enforced by its own institutions. But the attitude is very much to decide what rules to enforce based on ideological and political concerns, so the laws are largely meaningless.
