Re: Business as usual, then
"I suspect that one motive might be to grab the bandwidth licenses and go into business selling terahertz WiFi access points into the SOHO market. But with the obligatory monthly cellular bill instead of being consumer owned and free."
If that were to be something that might be considered, the incumbents would object to the need for licencing at all. Short range signals barely able to escape the room they are broadcast in is pretty much the definition of unlicensed spectrum. There would be a LOT of "stakeholder" reaction to attempts to licence that type spectrum.
