You say it needs an expert.
And yet you post a video by Stephen Fry who is no expert but a tv entertainment personality who is no expert but a fanatically biased anti democratic remainer who wants to ignore the result of the referendum.
I am all for a rational debate and accept that many people have different opinions but for heavens sake do not put forward such a one sided argument as something we should listen to . He is no expert.
To my mind experts are not needed all of their prophecies have come to nought about the impact of Brexit.
Putting aside all the self interests of people it is a very simple question for any country, do you want right to govern yourself or not?
