Earlier quoted context omitted.
It isn't valuable because "we" say so (whoever "we" is). One reason it is valuable is because millions of dollars of energy resource is put into it to ensure that it is decentralized
That's a ridiculous misunderstanding of value. Just because you waste valuable resources to produce something doesn't mean the thing you produce is now valuable.

True decentralization at this level is why it is valuable
