Without further reduction in battery costs, this exponential growth will turn linear again.

You are right on that. But of course, there is no basis for assuming battery cost won't decrease anytime soon. We're looking at decades of progress coming from material science research, economies of scale and learning effects, entirely new battery chemistries coming to market, etc. Any plan that assumes none of that is going to happen would be pretty weak.
