Now that is exactly the type of answers I was suspecting. Thanks a lot to make it clear by getting into the basics principles of passive investing, still have a lot of reading to do.
This, and the arguments in the “you-don’t-live-in-a-fairytale” line, in contrast, don’t stand a closer examination. Individual actions don’t stand a chance when taken alone, but begin to make sense when they repeat themselves. It is kind of like when your boss/relatives/media tell you that your personal vote don’t matter in an election or when they tell you that saving little sums of money won’t make you a millionaire… which we know is not exactly how it works 
It is just disappointing that all those big mustachians lumps of money can’t have a “voting/weighting” impact when silently growing to FI.
