Interesting, & not necessarily in a good way. This method could well presage unprecedented numbers of attempts at eminent domain takings or other means of forcing people out of their properties.
Which government agency would use eminent domain to take land and start mining? We have historical precedence with the oil industry using various scanning methods in a similar manner, but it was the oil companies who went to the landowners to acquire the rights to extract. Then the government would buy the (usable) product from them.
Local government condemned a bunch of perfectly fine homes in Wisconsin, by declaring them blighted, to make room for a Foxconn plant which never really panned out. Where there is greed there is a way.
