I think in the far future, cloud computing and the web will morph into a single entity where you will login to your cloud. This idea of identifying yourself prior to accessing your resources and having your resources connect to others doesn't seem far fetched anymore.

Especially with the way we are moving. Most people today are happy to use sso with services like facebook or google. Most people also have their real identify tied to their core profile they use to sign on to other services. The abstraction between the internet and the cloud is becoming more blurry to a internetizen that is technologically ignorant.

you do have to provide your ID to connect to the Internet, except for the prepaid anonymous sim cards paid for in cash.

Which are unavailable in many EU countries already.

Practically the only way of connecting anonymously to the Internet is the old-fashioned wardriving, or getting lucky and finding a "free wifi" which is not limited to the Web only.
