"But I find it to be terribly irresponsible to go out further than you can save your own self and rely on pushing the button. Now you are relying on someone else to come and rescue you. Why not cut back on how remote you go or how far you try to push yourself instead?"
It ain't that simple, Diane. Simply put, Sh!t happens, and in many cases it has nothing to do with exceeding your capabilities. Things can go wrong on a simple day hike. Things can go wrong on a short weekender, etc. And, as I mentioned earlier, SAR folk are going to come looking for you once you turn up missing, whether or not you "punch the button". Punching the button can save them a lot of time, effort and, potentially, risk, not to mention saving your bacon.
