Yes, exactly. Nations gave away sovereign, constitutional powers literally after their populations boldly rejected the terms, in a fair and open democratic processes.
Other European nations, verging on 'voting no' were denied the chance precisely because the EU apparatus knew what the outcome would be.
There's basically no defence of that issue, and the patronizing arguments defending 'indirect' nature of democracy of the EU wear thin - voters have no material impact on the EU, which is how it was designed, very much on purpose.
The limitation that MEPs have no ability to introduce legislation or frankly drive any of the real legislative process is by design.
It's mesmerizing to watch legions of young people defend an undemocratic system that their ancestors literally fought for 2000 years to overcome, with literally millions dead. 'Reason' lasted only one generation, before ostensibly well meaning actors took away the rights of the plebes before their eyes, and convinced them that it was in their best interest.
There is obvious need for reform, and if there was, I'll bet Norway and UK would be part of it, and possibly even Switzerland.
