Well...yeah, exactly. We already follow EU regulations in most cases, so unless people are aware of which specific rules and regulations they want to be repealed, and areas in which they want to diverge, the whole things seems incredibly pointless and unnecessary. We won't need to follow EU regulations...but we're probably going to keep on doing so anyway, because in most cases those regulations are fine and we don't have any issue with them. The only difference now will be that we no longer have any say in creating those rules, many of which we'll continue to take anyway.
I don't disagree that it's by far the best option for Brexit. But thus far I've yet to see anyone give me some specific things which we're going to benefit from when it comes to this, other than some vague rhetoric about not having to follow certain regulations which we already follow and will continue to follow.
