I disagree; leaving the EU is a perfectly well-defined action/goal, which isn't particularly difficult to achieve (we'll be out of the EU at most 2 years after invoking article 50). The referendum result was in favour of leaving the EU, so that's what should happen in order to maintain any semblance of democracy. There is certainly a huge space of possible strategies to take, but that's always the case with any political action. The UK government is elected to take such decisions on our behalf, with various oversight/transparency/legal conditions attached, so that's what should happen. I don't see how this is any different from a goal like "increase Britain's GDP"; there are many ways to do it, huge levels of disagreement, the elected government will choose a strategy they think is best for themselves. The threat of regular elections is designed to align the government's selfish choice more closely with that of the people; universal education is designed to align the choice of the people more closely with the will of the people.
