That is not the main reason. Not even close. Here’s a list of main reasons, in no particular order:

- 8 different currencies across EU member states - 24 languages - 27 sovereign countries with wildly different economic, social, foreign, military … policies - laws and regulations are only slowly harmonised across the board - deep seating historic prejudices (which lead to major wars in the past) - unfriendly and downright hostile neighbours - a smaller amount of natural resources to exploit - etc etc

How many wars were fought on European soil between 1776 and today? I couldn't even begin to answer that.
