> If every nation state operates by different rules that's not good for multi-national corporations. Multi national corporations don’t really care whether the rules are homogenous or not, they’re big enough to do whatever they need to to sell their goods and services in whichever markets they want. The single market was actually more of a benefit for smaller companies, allowing them to sell to 500m people without having to worry about customs declarations, country specific safety certifications etc. There are many many examples of small producers having to stop selling to EU customers after Brexit because of the added cost and bureaucracy.
