This has been already said, and OpenID has the same problem

WebID goes further in allowing us to create more trust around  
universal authentication :

- Semantic-enabled social networks are appearing everyday, add the  
ease of setup (just host a FOAF file)
, this will spread the risk of having millions ID stolen. OpenID is  
hard to implement, WebID democratize universal authentication , making  
it easier than SMTP to deploy

- If you have a critical application and allow people to use WedID,  
nothing prevents you to use more tools to know better who are your  
customers. A bank using WebID could ask for an email confirmation when  
detecting a change in the public key used (using a cache), ask a  
special question, define authorized computers using cookies ...

But these are extensions/plugin that could be standardized later
