Exactly it's in the EU's interest to deal with us as they will be losing more than the UK's contribution payment but a lot of trade to our rest of world partners if we leave with no deal. The only reason the figures are that high is because of European restrictions on our trade to rest of the world over the years. NO DEAL ALL THE WAY!!
Don't be too surprised if your "rest of the world partners" turn out to be more interested in access to the EU single market, than in the UK's market.
