"Which still ties you to the 'grid' insofar as you need the natgas supply chain, even if you have a huge reservoir you'll eventually run out. Having said that, batteries and solar panels don't have an unlimited life span either."
That is my thought - however, a previous comment in this thread indicates that the powerwall batteries are cloud connected and remote controlled by tesla ... so I am not sure how that pans out when you lose power and network connectivity at the same time (as happens where I live several times throughout the winter, sometimes for 24+ hours).
