Fokker, wasn't having a go at you, I simply couldn't resist the obvious gag! I wish there was an auto /Sarc tag.
In all seriousness, the $2 billion valuation has nothing to do with your valid metrics, rather, its what someone else is willing to pay for the entire enterprise. The claimed "fly away" price is in the vicinity of $2 billion. We are talking different things, you are talking logic, reason & accounting valuation. Those familiar with the situation are talking about the valuation of entire entity as a trading asset, not conventional business metrics. We are comparing Fuji's with Cherries.
