Yes, we read the same post.
The EU is not going to endanger nearly 20 percent of their economy to make a point. It would be far more dangerous to damage the EU economy than the optics of a successful Brexit.
There is not any leverage on either side. Both must get along and negotiate a mutually beneficial deal, or slit their own throats with a childish tantrum.
Yes, I agree they will cut a deal. This will probably happen after months of threats and bluster from both sides. It definitely won't be a pure "screw the Brits" deal. It will contain a few concessions, probably minor restrictions on free movement, which May can point to as victories. These will be the exception rather than the rule. By and large the post-Brexit economic reality will probably resemble the pre-Brexit reality, except that Britain will exercise less influence in EU affairs. The market access will come at a price. The notion being touted that the UK is sufficiently important by itself to set the terms of the deal it wants is simply wrong.
