Unspoofable GPS could fix so many issues, including Bitcoin power consumption. Is it possible? Time of flight from a satellite? Unique cosmic radiation values?

Isn't protecting uniqueness a problem? I can break into your house and sit at the chair you normally buy LocationCoins at.

Yes! We’ve had that bug for thousands of years and developed societal solutions to it (locks, police, etc).

Most people don't keep a ton of untraceable cash at their house, though. I think another application would be to use this unspoofable location to enforce a geo distribution in PoW systems. Can't build up big warehouses of miners.
