The UK was definitely the country which stood out the most in EU, so after Brexit, the EU lost one furthest away country in its block, in terms of diversity.

EU law cover stuff you hardly run into. Sure, you have euros everywhere but they don't regulate how much taxes you pay or how your national health care is managed.

All is fine until they start regulating on things that matter. Immigration is definitely one of the first sector where people started noticing they're in the EU, because they're unhappy with the results.

EU law makes news. It doesn't make many obvious appearances in day to day life when you're living there, however.
