I imagine this is all part of pre-negotiating strategy, letting the EU know that we will walk away from a bad deal.
And do you seriously think that the EU isn't fully aware of exactly what walking away with no deal will mean for the UK? What planet are you living on, roses?
Here is one of your derided experts on the economic effects of a number of options:
This blog provides a range of projected impacts on UK trade of these policies. In particular, we examine the impact of 1) replacing the UK’s single market membership with a free trade agreement (FTA) with the EU and 2) concluding new trade deals with non-EU countries. We find that if the new trade deals are similar to those already in existence, then their benefits will be expected to be very small compared to the costs from leaving the EU single market.
Specifically, we expect that leaving the single market will be associated with a long term reduction in total UK trade of between 22% and 30%, depending on whether the UK concludes an FTA with the EU or not. The estimated increases in trade from concluding FTAs with all of the BRIICS, are much smaller at just over 2%, while concluding FTAs with all the Anglo-American countries (USA, Canada, Australia and New Zealand) is associated with a long-term increase in total UK trade of less than 3%. This stark difference reflects that the single market is a very deep and comprehensive trade agreement aimed at reducing non-tariff barriers, while most non-EU FTAs seem to be quite ineffective at reducing the non-tariff barriers that are important for services trade.
