One might (& probably should) choose to evaluate things differently in places with different weather patterns than yours (higher humidity, seasonal ice/snow, & some degree of periodic storage, even if temporary). Whether you buy the best gas available or not is up to you, regardless of location.
I know from personal experience that the stuff works. FWIW Dale Walker (engine builder & tuner in CA) also recommends a periodic application of Techron to keep the carb circuits clean.
To make an unsupported statement that the use of Techron is a waste (however clever the analogy) without defining why or what assumptions you base that opinion on, or your specific experience with it, isn't all that helpful, IMO (but hey, that's just me).
