Because we're talking here about a file that one might possess within one's personal effects and papers--a file, on a PC, with no desire whatsoever to share it with anyone--the comparison to waving a knife around while screaming threats, or forcing a malicious file into a server, seems more than a little thin. Where is the motive? Where is the criminal frame of mind?

Remember, piping /dev/zero to a compression routine for a few seconds, out of curiosity or testing a shell script or whatever, could create a file that might throw a wrench into poorly-built works.
