You must be a blast at cocktail parties then.
>Stationary battery storage soaks up power when power is cheap, releases it when the cost is higher and energy demand is higher and has a 10 year minimum life
I think you're making a few unsubstantiated assumptions here. Primarily that the cost differential in electricity (or the availability of renewables) is broad enough for the Tesla tech to be significantly profitable.
I ran the numbers: a Tesla PW2 gives you ~20.3MWh throughout it's useful life for $5500 limited by power availability and recharge rate. A slightly more powerful Ford generator at $1500 with $4000 worth of diesel fuel would yield ~8.9MWh of anytime power with the ability to run on waste oils and a comparatively perpetual lifespan.
So, 44% the power cost with a power wall but a substantially higher upfront cost, a considerably lower salvage value, and a number of restrictions on it's usage (hope you don't need power during sustained outages in the Northeast).
Any more chuckles?
