For air: The 60GHz allows reduced cell size. This makes it more realistic for you to opt out of receiving everyone else's emissions (by walking away). Also, air is not not "fundamental to biological life" (anaerobic organisms exist). More seriously, at 60GHz and above skin penetration is very, very shallow.
Active denial systems use a slightly higher frequency (95GHz) and much higher radiated power (30kW-2.5 MW says Wikipedia).
The social aspects of IOT have as much to do with 5G as with, say, smartphones in general. That's just anti-tech. It can be discussed, but it's not an interesting argument in the context of whether 5G is harmful.
You are making emotional arguments that are not grounded in technical arguments.
