If people aren't willing to pay money for a service then they probably aren't willing to pay with integrity/information either - if they can avoid it. So failed paywall and micropayment experiments are probably a sign that the web site has an unsustainable business model.

A better system for micropayments would certainly help here though - most people who won't pay likely don't want to register an account at a third party service just to pay a dime to a web site.

I think this problem will be solved simply by the fact that traditional ad (network) revenue will dry up.
