Anarchy, here is perhaps the most egregious example:

Other examples include such ridiculous rulings from Brussels as forcing certain vacuum cleaners, toasters, hair dryers and even tea kettles off the market in the UK. (Really big mistake because anyone should know you never mess with a Brit's tea.) They want to impose a tax on cow flatulence more commonly known as farts. (Man, is that a load of shit.) They also want to stop UK butchers from packaging pork kidneys in the same package as pork chops. I have no idea why? The list goes on and on and is a great example of an overseeing bureaucracy gone wild trying to take more and more power.
Prohibiting the sale of some household appliances because they are not energy efficient is hardly an EU issue, and its hardly an example of a nanny state. Further, the toaster and kettles ban was never actually put into law, and is only being pushed by Juncker after the Brexit vote. Energy efficient appliances are common in every developed nation, including the US. It's just a talking point for people to whine about to hide other underlying issues.
The pork kidneys is just a complete myth.
