The claim was that no one would have any faith in it though ^^
It just means "very few people".
Else we could never say "no one" in casual conversation for anything, because even the vilest/stupidest/most paranoid idea still has one/some proponents.
(And by "even the" I mean, "most", not "absolutely each and every vile/stupid/paranoid idea has one/some proponents").
The original comment was unequivocally wrong. People obviously trust it.

Doesn't that mean that Bitcoin remains irrelevant -- (and 5 times less relevant today than when it was $5bn/daily).
So much for the future of currency...
