Internet scores higher than running water for me on prioritization, but I still couldn't bear to waste the resources to have a sat uplink for the 1-2 days a year comcast goes down. Taking a slot from somebody that actually needs it feels off to me too. It would only likely be worth it if your particular area has abnormally bad comcast uptime.
That said, we just purchased a beautiful rural property with a wonderful house, and will rent it out until starlink or fiber( local company is 1-2 years out) hits it. So maybe I'm just sore that people are taking starlink slots when they absolutely don't need it and its 2 years out =P
