Note that you are somehow arguing in favor and against the efficient market hypothesis at the same time.
By arguing for ETFs, you are implicitely assuming that there is not much to gain by doing your own research because markets are efficient and have already priced in everything.
By arguing that most people underperform the market, you are implicitely assuming that it is easy to underperform the market - something that should in fact be hard if markets were efficient and everything priced fairly.
