We agree in the main. My point is one of where we put the emphasis.
My counterargument, if it is one, is simply that when humans actually have faith in something, it's almost always "trusting what I don't know is going on, because of what I know of this object in other circumstances".
The husband "trusts" his wife to be faithful, not because he has a tracker on her and so knows where she goes at all hours, but because he knows who she is when she's with him.
A soldier "has faith in" in the general's battle plan because of the general's past victories.
I'm just arguing that all the really useful definitions of faith imply that the trust is actually rooted in knowledge and past experience, not merely blind, hopeful, stick-your-fingers-in-your-ears-and-sing-la-la-la ignorance of reality.
