You forget to mention that "conspiracy" theories try to explain significant social and political events. If I told you that you have a 5% chance of dying if you entered a building I engineered, would you still enter it?

Also, it often takes a lot of time for a coherent and full picture to emerge. Typically only after the powerful stakeholders have long passed away. So 5% may be an understatement. I recently watched the documentary The Spider's Web: Britain's Second Empire on Netflix > https://www.imdb.com/title/tt6483026/?ref_=nm_flmg_t_2_dr

It took more than half a century for it to come to light. My interpolation, yes my own little "conspiracy theory":) ...these facts seem to put the Brexit hurry in a whole new perspective. In 2014, the ECB became responsible for supervising banks in the euro area. In 2015 Cameron prepared the 23 June 2016 referendum and the rest is history. Just a working theory of a conspiracy :)
