There is a misconception that Leave voters believed all that politicians told them. This view is a conceit of both politicians and Remainers.
Politicians because they are often conceited anyway, and Remainers because of a belief they followed logical research and anyone who disagrees must have been swayed by lies. Believe it or not, many Leavers did research the facts so your idea that the future of Britain rests on Farage's opinion is wrong.
I can understand how Remainers make this mistake as many of the Leavers interviewed for TV etc were not the most articulate. It was as if they were chosen to portray a stereotype. Some were outright racists and many uneducated.
However, the fact that over half the voters wanted to leave the EU should be evidence enough that the selection of interviewees was not representative of people who voted Leave.
Actually, I do not think all Brexiteers actually believed the politicians telling them to leave.
Farage's impact was indirect.
He stirred off the initial debates, rightly or wrongly. This got the Tory knickers in a twist. Cameron then did the usual superficial analysis and bet all on party unity.
And then the referendum got called.
So in this sense Farage was the instigator. His opinion drove it whether people believed his facts or not.
Again, interestingly, people voted Brexit for a number of emotive reasons. I have met people from all walks of life who have done so, but on average they tend not to be the professional middle class educated types. Old money over 60s that I know voted Leave to great despair of their children for example. In them I think childhood memories of Britain on its own played a part.
Not all who voted Leave are xenophobic. But the problem is that Leavers did almost no worthwhile analysis. Zilch. Sound bites aside no neurons were engaged.
This does not mean Remainers had much better arguments. The point I explained to everyone from the beginning, including a current senior cabinet minister, was that the worst decisions are those where value is uncertain but greater uncertainty and risk more so.
You don't go into business, trade, war or any act unless the opposite is true.
And this to my mind this is the great mistake of the Leavers.
They have let a vacuous and rather incapable lot lead them into a situation with increased risk and no clear tangible value as yet. Rather stories are beung made up. About China, Japan or Commonwealth. Exports on back of weaker sterling without discussion about what products and services could become more competitive in the face of a weaker currency. Car exports? I do not think so. Large scale engineering? I don't think so.
I want to see detail. But detail is conspicuously by its absence.
The politicians throwing sound bites around, along with media and journalists, are entirely bereft of analysis and understanding. Not only so but they seem disinclined by nature to be able to do other than vacuous sound bites.
The positive feedback loop in this case (and I use it in the sense of mathematics rather than social good) is extremist politics leading to right wing shifts to more established politicians pandering to the shift, leading to further reinforcement.
In the meantime analysis and sober thinking and planning suffers. The politicians have shown that none of them have GB at heart, and simply lack the acumen and independence to rise above and do some sober analysis. They are the problem rather than the solution.
