Apple's prices have been higher in Europe for decades. This has nothing to do with regulation. You could maybe argue, that localization of th software does add some cost.Yes, because doing things like complying with ridiculously expensive, overbearing regulations that gives away IP to competitors costs money, and that gets passed on to customers in those regions.
I think it's just a pure marketing decision. Apple has a much lower market share in most of the EU and I would argue that consumers here perceive it more like a luxury brand. They could lower prices to increase market share. But apparently it's more profitable to stay where they are.
