Actually European integration the last 30 years has been pretty remarkable. In the past, not even electric plugs were compatible. But the EU is not a country. A lot of the inefficiencies are actually features sought by key members to protect their own local incumbents.

Your best example of European integration is electric plugs?

Money transfers between bank accounts for no extra fees (well, that's limited to the Euro, so a couple of countries chose to stay outside). Mobile phone usage for no extra fees all over EU (some limitations, but typically not relevant for the average trip).

B2B the integration has even bigger impact.

I don't think eletric plugs are even regulated. British plugs never changed and they were not an argument in Brexit.

Free cellphone roaming is a big plus.
