To repeat the original point, the "value" is driven by supply and demand. There is no intrinsic property of breakfast, like weight, color, dimension, in units of $$$.

I don't see a need to "justify" the price. They aren't forcing you to eat there, as you demonstrated. (btw, who's Mr. M)

Personally no, I would never pay that, and never have. I don't think it's "worth" it. I suspect Larry Ellison/Bill Gates would have a different viewpoint.
