Fees are not the only cost of business, compliance is too - and things like if you want to enjoy lower intra-EU costs then you need to be in the EU which is an added cost as a non-EU business, etc - it's not as simple as "fees more eu bad"
You're kind of agreeing at this point, despite what the EU believe they are not self sufficient and require international business - the only people who lose out by that not happening are citizens and there are already enough reasons doing business (or even buying) stuff from outside the EU is a tedious and expensive chore
