ETTR can make a much better than "good" photo especially in low light conditions. The benefit of ETTR in good light is not so much. But no-one is saying everyone must use ETTR for every shot. In some situations it just isn't practical to ETTR to its full benefit.
That is you opinion as is obviously your right to have but I haven't seen anyone say that a technically perfect raw file is the defining factor of making a good photograph. It can be a factor but not the defining factor.
No-one is forcing you to read or contribute to this thread so it shouldn't be of any concern to you if those interested in the topic do.
