Its logic like this that makes me cringe a little... There is no reason to think that other car manufacturers will buy batteries from Tesla, or even use the same chemistry/technology that Tesla uses.
Furthermore, the idea that by owning an EV, or the entire world using EVs, makes the world a greener place is far from reality. Yea maybe one day when all of the world's energy is solar, wind and hydro that may be true. But that is a lonnng time from now (several decades at the very minimum). The recycling process of the metal casings for batteries, the car body etc. are all extremely wasteful, not to mention getting electricity from the US grid...
Finally, the name of the game is to make money, not helping the world. Investing in tesla because you think the company will do well, and you want to make money off it is fine. To think that by doing so you are saving the world is just fuel for the bears to feed on.
Almost nothing you have said here is correct.
First, there is reason to believe that other car manufacturers will buy batteries from Tesla, because two of them already do buy batteries from Tesla. That seems like reason enough for me.
Second, owning an EV and the whole world using EVs definitely makes the world a greener place, even without doing anything whatsoever to the electrical grid. Check this link to see that no matter where you are in the US, an EV is cleaner than a gasoline car:
Global Warming Emissions and Fuel-Cost Savings of Electric Cars (2012) | Union of Concerned Scientists - you can see the same thing on Tesla's Go Electric page, broken down by state, using US EIA data. Also, EVs get cleaner as the grid gets cleaner, which is not the case with gas cars. *And* you can install solar onto your house and immediately make your EV 100% emissions-free, which is something 30% of EV owners in CA have done (according to a recent survey of EV owners in CA), so don't think that this is some sort of niche application. All cars have bodies so to say that an EV takes more to build or recycle is silly - it takes a slight bit more energy to build an EV and the EV uses massively less over its lifetime, because cars use a vast majority of their energy during operation, not production (there are many studies and common sense showing this, but I can produce one if you're that skeptical...you shouldn't be, though, it seems pretty obvious). Recycling, also, is not a huge issue, as lithium ion batteries are non-toxic and can even be landfilled, not that they would be, because they'll be reused in low-draw applications like grid storage which offer additional efficiency gains after they are out of the car, and then if it becomes economically viable to recycle batteries they will be recycled (it currently isn't, not because it's expensive to recycle them, but because it's so cheap and easy to get lithium). Regardless of this, some firms already have ~90% recycling efficiency for li-ion batteries.
Really, I have no idea how you can be so woefully misinformed about this point if you spend any amount of time on this forum. It is unequivocally true that EVs are better for the environment than gasoline vehicles according to anyone who has given the least bit thought to the issue.
Finally, the name of the game, explicitly, from the top of Tesla, is to accelerate electric vehicle adoption. That's the name of my game as well. If I make money on the way (as I and everyone here has already done), fine. If I don't and all I get is a longer life and get to breathe clean air and leave a better world for all of our children, then I guess that's just a terrible thing isn't it?
Speaking of bear fuel, every environmental concern you've brought up is explicitly bear fuel, and is completely false. So please do not accuse others of spreading bear fuel when that is exactly what you are doing.
