It's very commonly the anti-EU politicians who inevitably get into EU parliament (due to representative voting, ironically more democratic than the FPTP system we use in the UK, despite all the wailing about democracy) who endorse such obviously stupid ideas, as a way to undermine the credibility of the EU.

What's frustrating is that it works really well, and occasionally they get something truly stupid through- which goes a long way to whipping up anti-EU sentiment, but then they're forcing their countries to actually do the stupid thing... Nobody seems to call out this self-sabotage.
