To answer the question, it seems pretty straight forward that paying more for a supplement that has no benefit over a far cheaper supplement is irrational. If you deny it has no benefit over whole protein, as the writer claims, that is one thing. But if you accept that hypothesis for the sake of argument, as you do in the quote..well it seems entirely obvious why it matters that BCAA has no benefit over, for instance, a whey shake. 
Studies can be wrong, no question. But the concept of doing clinical trials which are well designed, use real measurable criterion for gauging effect, and which are done with a sample size large enough to remove any reasonable chance of the results are due to chance....that concept is the foundation of modern scientific progress. The most important lesson for any researcher is that YOU CAN BE FOOLED. The placebo effect and many biases inherent to human thinking must be consciously and carefully eliminated. If not the result is not reliable.
Anecdotal evidence is quite nearly the WORST and least reliable form of evidence there is. Do you know how many millions people spend on homeopathic remedies each year? All of these people are taking placebos and many many of the people will claim that they work. You are not immune, I am not immune. 
The reason you don't feel that you can rely on journal articles *may* be because you don't know how to critically evaluate them. That doesn't mean you are not very bright, you very well may be. But it is a skill that is not natural and must be taught and practiced. Some studies are totally worthless because of methodological errors and unconscious biases in the collection and interpretation of data. But saying "well I felt like it worked" just doesn't cut it.
