That is not a good analogy. There is such a thing as reasonable expectations when visiting a website, so you do not need to read the TOS. Otherwise I could put "you own me $1000 for visiting my site" into the TOS. In other words, just clicking on a page does not constitute entering into a contract with the website. Registering and accepting the TOS does, but that still doesn't mean that anything in the TOS is enforceable.
