> Elon has seen the same balance sheet and he thinks the true value of the company is higher than what it is now as well. So obviously he thinks Twitter has the potential to achieve much higher value through implementing XYZ. The board agrees too but just disagree on what that XYZ is.

Yes, but one version of XYZ (the board's) has been tried while the other (Elon's) has not. Elon's plan might lead to even worse results than the board's, but he doesn't think it would, hence his optimism if they adopt his plan.
