Been there/done that - Sweden was unjustly bullied by China and got next to no support from EU. That was a mask off moment for some of us. It seems that for member states like Sweden and the Netherlands, we're supposed to just pay a lot of money in order to get toll-free access to the internal market.
Edit: I would welcome a split into EU North and EU South. Sort of like Aldi North and Aldi South.
EU North: UK (welcome back!), Norway (hello!), Denmark, Sweden, Finland, Netherlands, Estonia.
EU South: The other countries.
