You said: >>If a situation does not enter into an area of federal power outlined in Art. 1 Sec. 8 of the Constitution, it's really none of Fedzilla's business. This is the part of the Constitution (Article I, Section 8) that permits the FCC's regulation of the radio spectra: To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes;
This is a proper interpretation of the phrase "regulate Commerce...among the several states, and with the Indian Tribes" aka "Commerce Clause." Most applications of the phrase, as used by the present "Fedzilla," are improper, which makes this one of the rare ones that are proper.
The bolded section is what is relevant. Yes, I can broadcast around the world. Because it crosses state (and even national ones), then federal, and even international regulation makes at least some sense.
In the case of little 5 watt microbroadcasters, I don't really think it does. I have a small TV transmitter that will reach analog sets that are about 500 feet away from the transmitter. I don't think the feds have any business regulating that either. Some regulation is useful, as without it, much of the airways would probably be pretty useless, because you'd have bozos indiscriminately stomping on everyone and preventing the use of most of the spectrum. This could seriously impact people in a negative way, especially in times of a disaster, like a hurricane or something of similar scale where often the only comms in some areas immediately after is radio.
However, just because some regulation makes sense doesn't mean that indiscriminant regulation does, which is sometimes what Fedzilla does, and often times is doing in the case of microbroadcasters.
