Representative democracy, with it's paltry accountability except every 4 years, gerrymandering-schemes (not a US-only problem), typically revoked election promises, backroom talks, corruption, and private interests paying politicians is already undemocratic enough as it stands.

And suddenly removing the voters even further (as in the EU Commission), or adding "bodies" with no officially defined role and protocol, and closed discussions, like the Eurogroup, is "democratic" because those involved were "democratically elected finance ministers" under unrelated to the EU national elections.
