There is: EU citizens can engage their peers in dialogue on how this behaviour is terrible and they can try their darnedest to convince their peers to never vote for politicians who are part of the problem.
Yes that will work. Just like referendums work in the Netherlands for example. 90% the population vote in a referumdum against a particular agreement. The government voted for it anyway and then got rid of referendums.
I would prefer to have decentralised government. This centralised rules for millions doesn't work and eventually escalate badly.
Just because we give up our responsibility to electorate in hope that they solve our problems. How could they possibly do that for millions of individuals with different problems and needs?
That's how effective and democratic this all is.
