I could put my absolute best reasonable argument that bananas are blue. Doesn’t change the fact that, no matter how polite and reasonable my argument was, bananas aren’t blue, and everyone knows it. From then on the argument stops being reasonable if I keep refusing to look at an actual banana and somehow reconcile the ideal scenario I’ve cooked up in my head with reality. In this case there are many small advantages, and one huge dealbreaker. One can’t just decide to ignore the dealbreaker just to achieve this reconciliation
