That's a fair point. The difference is in where I think the trust should be placed.

I would love to be able to pay for goods on Amazon with bitcoin, because I trust Amazon. Right now Mastercard/Visa/Paypal takes a cut on each of those transactions to provide "trust" in them that I neither need nor want. If things go wrong in that transaction, I'm still left dealing with Amazon, as Mastercard/Visa/Paypal will not want to get involved.

In cases where you're dealing with an unknown quantity, then you have to look elsewhere for your trust metric. eBay has their, eg. "99% positive" reviews, Silk Road has their own way of dealing with this (similar with freebies/samples to build trust).
