I see where you are coming from regards giving Reform a go at being in power to see how Brexit should have been done. Both Farage and Sir Jacob-Rees Mogg have said that the Brexit opportunity has not been used.
The risk for the Eton and Oxford brigade is that if Farage, Reform or another Brexit supporter became PM and proved that they had done it wrong, it makes them look silly. Hence, they don’t want any such person ever to become PM.
Since the 2016 referendum, UK has had the following PMs:
Cameron (Eton and Oxford) voted remain.
May (Oxford) voted remain
Boris - was part of leave campaign, but thought they would not win.
Truss (Oxford) voted remain.
Sunak - ?
Starmer (Oxford) voted remain
Burnham (Cambridge) voted remain
So, for as long as the UK has a PM who voted remain, Brexit will always be at the bottom of the pile in terms of their own personal interests. Some, might say that they will intentionally sabotage Brexit so they can say;
“The Eton, Oxford and Cambridge elites told you it would not work, but the peasants didn’t listen”
