I wasn't just referring to geothermal, I was meaning in general. We've stopped doing important and useful things because there's no immediate payout. But, geothermal has properties the above ground and easier options don't. A sense of permanence that storms and clouds can't affect. Always running. That's very valuable. Yes, if you need a kWh, there's cheaper and easier ways to get it. If you want a source of heat and energy that exists when everything else is broken, it's hard to argue with it. A city emergency shelter comes to mind.
