Have a look at my last reply to George Hincapie on power and sovereignty. That's what I think it comes down to.
But re Gove's stance, like the PM, I'd never find occasional frustration on its own a good reason to leave any big organisation with demonstrable economic advantages. Besides, we haven't been treated like a second-rate member over the decades: exemptions, rebates, considerable input from British heads into the formation, rules and law governing the common market and human rights, etc. This latest emergency summit and deal is only the latest in a long string of special treatments.
Lastly, a lot of what people moan about rule-wise, is actually what makes the common market flow smoothly. But because they are neither in business or understand the rules, they buy whatever second-hand information catches their attention most from a source that appears authoritative.
We should finally decide whether we can make having our EU cake and eating it tenable, or not.
