I would not call it a trap, I would call it a trade off. But I am quibbling over semantics. I would reference Shannon here https://en.wikipedia.org/wiki/Shannon%E2%80%93Hartley_theore... which essentially says the following: C ~= B * SINR ( see the link for exactness ) C is the capacity of the link (think bps) B is the amount of spectrum ( how many Mhz can I get across the medium ) and SINR is Signal to Interference and Noise Ratio

If you think about this, of course, wireless will be limited spectrum, there are only so many Mhz that is made available for whatever wireless standard you are thinking about, Wifi, 4G, 5G, Bluetooth, whatever.

And, obviously, wireless will struggle with Noise and Interference.

Wired solutions, whether shielded twisted pair (e.g. CAT6) or Coax, or Fiber or Waveguide, whatever, will do much better on SINR, you have thermal noise sure, but generally, it would be a much quieter medium.

Also, you would not have the FCC saying you only get X Mhz, whatever you can get across that medium you get to use.

Thinking about all of these factors then of course, Wired will generally win out, all things being equal.

The Trade off, is that wireless is more convenient.
