I didn't say there was a problem with it; I just asked what the reason for wanting it was.

So let me turn this around: Why do you think a system that doesn't make it difficult to completely destroy it with one command is a bad idea? "It's my system, I should be able to do whatever I like" is an answer, to be sure.

(N.B.: in fact, "rm -rf /" won't work without "--no-preserve-root" in most Linux distributions, AFAIK, and I presume sudo.)
