This is clearly anti-Tesla, but it's not really gibberish.

I think the author is using sound logic overall, but he's just a little misinformed on a few things in this particular case.
#1 The Company's Promotional Approach & Investor Sentiment
To me, Elon "takes time out to tweet taunts at short sellers" because he is a badass, not because he's trying to pump up the stock. However, I think he's right to be skeptical when a company is trying to avoid generally accepted accounting principles. In the end, you have to look deeper and make your own judgement as to whether you understand and accept Tesla's reasoning behind that.
#2 Lease Liabilities
I'm sure most of us here believe strongly that Model S will hold its value as well or better than any other car (due in large part to the lack of mechanical complexity in the powertrain, relative to ICE cars). From an outside perspective though, I can see how it looks pompous to make that prediction.
#3 The Early Adopter / Rapid Scaling Paradigm
Tesla's projections and goals are indeed lofty, but reading this part makes me wonder if the author has a) driven/ridden in a Model S or b) seen the factory videos and the level of automation being used. To me, the driving experience proves demand will continue to exceed supply until Gen III, and the automation they've achieved and rapid scaling they've done already proves that they can ramp up further.
#4 Competition
Many of us have seen "teething" issues with Tesla, but just because Tesla is a new company does not mean it is not stocked with experienced people. BMW's ICE loaner program is a nifty idea, but it's also essentially admitting that they're selling an inferior product. Tesla's combination of range and Supercharging has the potential to virtually eliminate range anxiety. No other car manufacturer has announced any plan that competes on that goal, and the longer they wait, the more difficult it will be to catch up. Normally I might expect extremely large companies like the "Big 3" to be able to overcome deficits like that, but these are lean/difficult times for auto manufacturers in general, which reduces the margin for error.
#5 Potential Dilution
Another good point in a general sense, but I think a large portion of those outstanding options come from a recent convertible debt offering, which Tesla specifically hedged against. Honestly, I don't fully understand how that works, but I trust that it will minimize the dilution effect.
