You are talking bollocks.
The mono mix is representative of how the film sounded in 1977(to a lot of people)
Not everyone in 77' had the means or good fortune to be located in a major city to be able to watch it in 70mm and 6 track magnetic audio.
The vast majority would have experienced Star Wars during it's original theatrical run watching 4 generation degraded 35 mm release prints with the mono mix.
