However, the UK will lose the huge amount of influence it has at the moment on the world stage, will be pressured by bigger economies to accept unfavorable trade deals and deregulation (US food standards, VISAs, etc) and its manufacturing will be severely damaged; it could possibly collapse entirely. The irony is that this will likely create a wave of unemployment in the very regions that voted in favour of Brexit.
But regardless of the consequences, if you think people voted for a "no deal" when they voted Brexit, you are deluded. Let's illustrate my point with a few quotes:
"The free trade agreement that we will ahve to do with the European Union should be one of the easiest in human history" - Liam Fox - 2017
"Getting out of the EU can be quick and easy - the UK holds most of the cards in any negotiation" - John Redwood - 2016
"Within minutes of a vote for Brexit, CEO's would be knocking down Chancellor Merkel's door demanding access to the British market" - David Davis 2016
“It is also true that the single market is of considerable value to many UK companies and consumers, and that leaving would cause at least some business uncertainty, while embroiling the Government for several years in a fiddly process of negotiating new arrangements, so diverting energy from the real problems of this country – low skills, low social mobility, low investment etc – that have nothing to do with Europe.” - Boris Johnson 2016
As you can see, no deal is far from the position that was pushed to the people, even after the vote had occurred. Saying people voted for a "no deal" because they voted for Brexit is disingenuous. Long gone is the time of "Having our cake and eat it"
