To me it seems like that a revote would have to deal with the literal fear mongering the stay side has been pushing out. My personal favorite is the food shortages, while every other country outside of the EU manages to import food, apparently if you try to leave, you wont' be able to find the food you want on the shelves any more!
The EU would not blockade Britain, as many of these articles seem to imply (how else would you just run out of something simply because you have to import it from a 'foreign' country now?). Britain would have to pay any tariffs the EU imposes to others of course, but it would also be in their best interest to not set them so high that people in Britain stop buying their products at all. Any 'shortages' would be brought about by shear mismanagement.
The issue with the food is about the regulations on their import into the UK, having been in the EU for so long most of those rules are just the EU rules or really old out of date rules that were superseded by the EU food regulations. If there's a no deal Brexit all those EU rules go away and boom suddenly there's a big question about what food is legal to import.
