Is a bishop fienchetto a bad idea ?

If your goal is to show us all how a piece is more powerful in a general sense when it controls more squares...well, Bobby Fischer Teaches Chess, chapter 1 (I think, not positive which chapter) beat you to it when I was 7 years old ;). And, yes, that is a beginner's book.
Too many players seem to be disregarding my ideas as "too basic". I see many weak players in the low 1000s reading Silman's (good but advanced) HTRYC, and thinking they learned a lot, when I don't even understand the book myself and am keeping it to read it when I become stronger.

I see. I just don't understand the concept DEEPLY enough ;)...
It's just not that deep, I'm sorry. Everything you have posted is essentially a puffed up version of "a knight on the rim is grim"...
It's a basic concept. Whether players ignore it or not in various games does not mean they don't understand it well enough ;), they just choose to ignore it for a whole litany of possible reasons.

Bishop Fianchetto's are good, depending how open the diagonal is. If there are tons of pieces and pawns blocking, then probably is a bad idea.

If you say so...Although these "litany of...reasons" are the things causing poor moves.
You can't believe this though? Putting the knight on the side of the board is in many mainline openings, it's not a poor move.
Sticking to terribly basic concepts - your piece is more active it controls more squares, a knight is worth 3 points, doubled pawns are a weakness etc is more likely to cause bad moves.
The basic guidelines are just that. The position is key.

What if every debate was in the form of a rap battle?
Then Eminem would clearly be a GrandMaster Blaster.
This thread is just one hairsplitting exception after another, regarding the topic of "controlling squares."
Oh woe with us.

Why "Grandmaster"? Rap and chess are not related.
