I don't think the dollar analogy is very useful. The kind of trust we place in money is a very specific kind of trust, and the risk we take in trusting money is generally limited to the denomination of the note or coin. This is so well-understood that most of us never think about it - though we may realize it's prudent to examine a $100 bill more closely than we would a $1 bill before accepting it as valid. OTOH, the appropriate kind and degree of trust to place in a domain name or CA for a domain name is not well-understood, even though it may be implicit. Keith
