You also don't care if the punch was warrantless or not. Here, we are discussing warrantless wiretaps, which has a specific meaning. You don't get to pick and choose which meanings you discard (wiretap) and which meanings you keep (warrantless) because goalposts can be moved forever, and communication becomes impossible.

Also, lawyers (ie me) are free to speak as private citizens. I could go on at length about the legal distinctiveness of content and non-content interception, but whether it does matter is different than whether it should. I don't see metadata as fundamentally different in practice than content. Scotus may say otherwise, but I am under no obligation to agree with them.
