This is ridiculous Brexiteer fantasy. The UK will have no measure of success in the short to medium term in a no deal scenario; it will be absolutely catastrophic.

It's meaningless to speculate what might happen in a fantasy scenario a decade or more later, but we know for a fact that the UK would be initially hurt much more badly by no deal than the EU.

If anything, no deal should convince Eurosceptics in other countries that they just cannot sell this fantasy to their constituents anymore.
