As a useful model, however, I think it works. Regardless of whether or not it's real energy, all I really want to know is if some things make it difficult to work (say social media) and some make it easier (working out). The battery is as useful a way to do this day to day as anything else, in my opinion.
I can empathise but wouldn't you prefer to know the true causes rather than fictional ones?
For that particular pairing, it might be self-esteem, how the individual handles other people's perception of themselves etc. If they can get a handle on the real causes, they can then build techniques to use SM without it being a drain and extract more benefits.
The reason I think its important and not just an optimisation is that one day, the gym might stop being positive. When the positives stop working, you then have a limited time window to fix the situation before you enter a downward spiral. IMHO better to get your hands on the real tools earlier.
