It's the opinion of many people that there are no "airwaves" UNTIL someone invests a lot of time and money to create the electromagnetic field.

The field does not just travel through "air" but also the emptiness of space.

I completely agree. There’s no such thing as a “natural” resource. Every resource is unnatural in that a human being had to first find its value and exploit it.

Look at anything ever.
