While that is the case, SO is designed to be as accessible as possible for even the most casual user. There are even stories about cookie based accounts that are ancient as far as I remember.

So the site tries very hard to require nothing to participate and as someone else already said, the 'more advanced' privileges are not useful for most people. Why would you want to edit questions in general, unless you're the OCD type or a wikipedia separatist? :)
