The fast-path TSA agents don't do the opt-out pat downs. They couldn't: the search happens in a semi-secluded area of the checkpoint, and the whole line would have to shut down if they didn't have people dedicated to that task. You do not in fact add 5 minutes for everyone else.
What is true is that you may end up in line behind 1 other person waiting for extended screening (if they don't have their ID, or if they got randomly selected), and you may add 5 minutes to those people's time. I have very little problem with that.
I'd refuse (politely) even if I knew I was screwing over the line, though. A strip search is a strip search. It crosses the line.
If I could get everyone to do anything at my command, I'd have a lot more fun with it than simply getting people to opt out of strip searches. Suffice it to say that chaos is not going to ensue, but a helpful amount of backpressure in the system might.
