We all have faith in one central aspect of our lives, money. Money isn't inherently worth anything, without faith in its value it'd just be numbers on a screen, bits of paper or plastic and funny metal discs.
I think you're confusing faith with trust. Money is not inherently useful, but a lifetime of experience exchanging said money for goods and services means that I can trust it as an abstracted medium of exchange. This trust can, of course, be lost. Just like how one can lose trust in another person. But I think it's a real stretch to call it faith, because I can and have used money to effect real results in the material world. I can't pray for a pizza to appear on my doorstep. Well, I can, it just won't work. But I can use money to pay a business for a pizza and make it appear on my doorstep. That works, I don't need faith for that.
