> the EU has the ability to fine foreign businesses for being monopolies too.

Specifically, the EU has no ability to fight foreign monopolies. Though, it has an ability to fine them and extort some pocket money from them. However, this hasn't had a tangible effect on creating more competition in those markets.

Then people accuse you of being "protectionist" or "mercantilist". Your companies aren't internationally competitive. This cripples your exports unless you can convince other countries to also block the goods that are undercutting you.
