That is not to say there are not elements we would want, but there are real and practical reasons why we would want to veto certain measures - anything from width of bridges to noise pollution measures. A one size policy will never fit all.
In this we are better off seeking a common set of values and adhering to common standards as agreed by the UNECE and having looser conventions rather hard coded rules. That is what most people assume directives are - and to my mind, that is what they are supposed to be - but in reality they are far more demanding - and we have to swallow them whole.
While it's true that Brexit in the first instance still means we would adopt such a directive, it does give us a free vote and a veto at the UNECE level (the real top table where the nuts and bolts are forged) and the EEA veto - which probably should be used on something as potentially destructive as the Port Services directive.
While I could really go to town on a post like this, it's actually besides the point. These measures are about as "ever closer union" as it gets and still we have no real means of exemption. Our relationship has not changed. As much as the prime minister has lied through his teeth and the EU is not being reformed either, it is actually only Brexit that can deliver the change in relationship the PM pretends he has secured - having the best of both worlds of single market membership and none of the political union.
It's unrealistic to ever expect we will have total control because we will always seek cooperation but it's clear that while we are in the EU we don't have the necessary influence to stop harmful regulation and if we did, it would be harmful to the rest of the EU - which could do a lot worse than to implement such measures.
