Batteries also solve the intermittency problem, for less money, and their materials are essentially 100% recyclable. Solar+batteries together are already cheaper than any other form of grid scale electricity production. Entire islands with thousands of people on them have replaced their fuel-based power generation with solar+battery and are seeing lower costs and higher reliability. If the economy is dysfunctional on earth, why is SpaceX a special snowflake company that is not also dysfunctional? It’s a US-based company. It’s publicly traded just like UPS. UPS has more competitors than SpaceX (FedEx, USPS, DHL, Amazon fulfillment, numerous B2C couriers, international couriers) Using the price of bottled water is not meaningful to this discussion. Bottled water is a convenience product, the water is not a significant aspect of the retail cost of the product. Bottled water costs $5 inside the airport and $.15 at the Costco 2 miles down the road. The water is not the driver of the cost. We only have one proven habitable planet and we need to protect it. Multi planetary habitation is some combination of 4 things: 1. Billionaires’ excuse to extract the earth dry for profit. 2. Billionaires’ fantasy to escape the pitchforks at their doorsteps, to build a gated community in the cosmos 3. Billionaires’ pump and dump investment vehicle 4. Billionaires’ science fiction affirmation of their narcissistic belief in their own demigodhood.

Batteries don't scale well when you're speaking of extremely high energy needs, especially given their deterioration over time. There's more clever things like artificial hydroelectric, but even that runs into scaling issues. Deep space solar, once established, has nice scaling potential. The inverse square distance:luminosity relationship really opens the door to some truly sci-fi type scenarios. SpaceX is not publicly traded. It's privately owned and operated, with Elon's motivation behind the company being consistently ideological in nature. The water prices were apples to apples comparisons - the cost of a 0.33 liter bottle of water in an average restaurant.
