You are advocating the complete abandonment of the
principles that
underly Wikipedia.
"You can edit this page right now." That's the mantra. That's the
key. That's what got us where we are. It's foolish to give up on the
thing that made us succeed where other things (Nupedia) failed.
The key underlying principle is making a free encyclopedia available
to everyone. "Anyone can edit" is simply a means to an end - it is
secondary to the goal of making an encyclopedia.
We should be working to make things better for the readers, not the
contributors. Relaxing our rules on using reliable sources would be
great for the contributors, but makes the website pretty much useless
for the readers.
