It is a logical argument. We are the only country with an exemption from ever closer union. Being in the EU, but the only country outside the the Euro would be a pretty lonely place. It is not something I want, but there are only two places worth being - fully in or fully out.
With regards to the use of Imperial measurements within the EU (also mentioned in the article) it was the US that successfully negotiated flexibility where the UK failed. Thank you America.
Brussels had forgotten that Imperial measurements are international, ancient in origin and based on the human body. France too used imperial measurements once. I remember visiting rural farmers markets in southern France in the 80s, where old women sold their produce in livre using hand held scales. They were so wrinkled, bent over and toothless that they had a mystique about them, as if they had been alive long enough to remember pre-Napoleonic France. The EU has run rough shod over that France as much as it has over aspects of life in Britain.
