The more proximal cause of "not believing warnings about no-deal" is that there were very similar warnings for the Brexit vote itself, and approximately none of them came true. Personally, I just can't see any big issues. Obviously UK's not going to ban the workers it needs or the imports it needs. Obviously other countries will still want to sell to a rich country like the UK. Sure, there might be a year or two of worse economic prospects as businesses and laws adjust, but really it's the long-term prospects that matter; and maybe it's better that UK unshackles itself to the EU which doesn't seem capable of thinking long-term and solving it's most pressing problems (democracy deficit, current account imbalances, immigration)...
