No analogy between online and offline worlds is particularly exact, but I prefer analogies about window shades, maybe including whether you can make window shades out of materials that block more and more of the electromagnetic spectrum (if you learn that your old window shades were transparent to infrared, for example).

Or Terahertz rays maybe?

The thing with real-world effects is that the channel to control this would be their ability to constrain IR shielding materials in the supply chain. But if they were ubiquitous, then I guess it's a good analogue: you would be guilty of the crime of attempting to hide your IR signature, not of any specific act done under the banner of being IR invisible.
