Not to mention Gibraltar - everyone's overlooked this tiny rock, but Gibraltar is entirely dependent on EU freedom of movement and voted very heavily remain. It's not a coincidence that there was a Gibraltar diplomatic mission to the SNP conference, although I'm not entirely clear what they wanted other than solidarity against Brexit.
Maybe Spain would let in Scotland and claim Gibraltar as their own?
Germans are going to face a large hike in their contributions to the EU in the next few years as the UK leaves, as the EU appears to be utterly incapable of actually spending less (despite now having diminished responsibility). That's just not in its nature.
So then Scotland comes along. The best available data says it's an economic basket case significantly worse than Greece. The UK subsidises it to a great extent for historical and cultural reasons that don't apply to Germany. Meanwhile, 40% of Scotland voted out of the EU as well.
If you're German and already questioning whether you should be subsidising lots of low productivity high debt Mediterranean countries, does the thought of waiving the entry requirements and then paying even more taxes to subsidise a new Greece appeal to you?
Don't know why this has been downvoted. It's on topic and not even a particularly controversial line of argument. I'd hate to think downvotes were happening due to prejudice, but it does seem that the left wing wants to suppress differing opinion these days.
