@izzythepush,
I think that it has been and stiil is a "buddy play" between Cameron and Johnson ....... and Gove now entered that competition as the third buddy (again).
It has been, in my opinion, just and only about about the leadership in the Conservative Party, with the EU and Brexit as the major trump [pun intended] card.
I agree that at the end, you'll probably end up as before but with no say in European laws and EU-organisations. (Selling German cars would be a minor effect: they can handle this with Norway and Switzerland.)
