In most of the developed world, the birth rate is either stable or in decline.

That's is true for now, but if we let people self select who breeds we'll end up with a population of those with a propensity to breed; either socially or biologically. We're going to have to stop that someday, somehow. I'm confident that it's far enough in the future that I won't have to deal with it.

Banning the trading of certain goods which aren't inherently harmful by themselves seems like a dangerous precedent to set.

The precedent was set by the outlawing of gold bullion ownership. I'm glad that's over, but governments have not promised to never try such a thing again. The control of the money supply is important to them.

The difference between the 60kWh and 85kWh Tesla Model S cash price is $10,000 or $400/kWh so I'm not sure about the article's conclusion that the battery costs $300/kWh.

In addition to the other points mentioned elsewhere, the 85 kWh Tesla includes access to their charging stations, which is valued at $2,000.

I'm very suspicious of the idea of used battery packs being used for grid storage.

However, lithium is cheap and is well understood. I think Tesla could devote some of their production into non-cobalt based cells, and possibly non-nickel too, and use them for stationary storage.

Whenever people agree with me, I always think I must be wrong. - Oscar Wilde
