Touchdown! Greaser!
Your points are well taken. While going through IR training does tend to result in improved piloting, ADM, and weather analysis skills one could gain equally valuable experience in other efforts (e.g. upset and/or aerobatic training, a glider rating, commercial ASEL, or even just plain recurrent training). And maintaining IFR currency/competency does require some extra effort and expense (an hour of simulated or actual instrument practice with a CFI every month or two should be sufficient for most) and without that effort the operational value and safety enhancement of an IR diminishes greatly.You'll get many differentiating opinions on this when it comes to private/recreational flying. I am IR, have been for a long time. Outside of using it a few times for private use, the rest of the times i have used it were for flying jobs. I have not done a personal flight IFR in over a decade because 2 major factors. I do not like it, to me a flight in the clouds is a waste of time and money, if I don't want to see anything along the way an airliner gets me there way cheaper. I also don't have a plane that I think is safe in most of the IMC conditions I fly in which in the summer is loaded with thunderstorms and in the winter loaded with ice.
The flip side to that is that I still launch VFR in conditions most would not accept to fly VFR in due to the low altitudes I'm comfortable flying at (one of the reasons I pay to fly a twin) and stay visual underneath. There are people who will argue that the risk there is higher than the risk if 'in the system'. I don't really argue back on this as those arguments have validity. We all make our choices of what we are most comfortable with. I have spent most of my career at sea and flying as well below the clouds watch and dodging the weather above. In fact, over half of my 2500+ hours has been spent below 200' AGL, much of it maneuvering at 3' AGL, that I am much more comfortable down where I can see what's coming at me. There have been just a handful of flights that required delays of more than 2-3 hrs to complete, and I have made it through the cross Florida T-Storm line on more than one afternoon that had airliners sitting in Miami and Atlanta waiting.
There is also the matter of maintaining proficiency in IMC. Without SVT, IMO this requires 50hrs a year of dedicated instrument flying (not just flying every trip filed IFR and flown in VMC) with 100+hrs a year total flying minimum. I don't have that time to spend nor the desire to fly that much IMC.
I've heard more than one pilot say they did the IR thing so they'd have that ticket in their pocket to pull out if they needed it some day and it just doesn't work that way.
But if you want the ability to take trips when the wx isn't CAVU at night or at least reasonably VFR in the daytime having an IR and keeping current is well worth the effort IMO.
