Though an interesting premise that acoustic treatments are poppycock, I find the OP to be that instead, and rolling this into the snake oil channel is just ignorant.
My experience was the exact opposite and by adding a few treatments to my room and a throw rug my audio enjoyment was increased by 10 fold.
Now I do thing is all works together and is part of the formula in the search for acoustic perfection, a goal we will never achieve. Treatments, furniture, cables and yes even fuses all play a part, but many not in every system or listening room.
Just go into this hobby or obsession with an open mind. A closed mind limits your friends, audience, and enjoyment and makes you a lonely and angry.
