Let me try to elaborate as concisely as possible.

OSM right now has very little tools to support editing.  Compare this to
text processing, where we have diff, patch, CVS and Subversion, etc.
The tools can't handle every case, but they do the tedious work and help
support higher-level functionality.  Wikipedia extended this to support
crowd-sourced editing, and has support for, e.g. detecting a reverting
vandalism.

Right now OSM lacks tools like that.  When a user like Josh Doe has a
data source with hyper-accurate road centerlines, the only way to
integrate that into OSM is manually.  When someone else destroys some
existing data, either accidentally or maliciously, we have to post to
the newsgroups to get an admin to fix things manually.

There is a whole realm of tools and techniques to support computerized
mapping that are waiting to be developed.  No doubt other groups like
Google, Bing, and even MapQuest are already working on them.

I really don't understand how certain individuals propose to manage a
large database with many contributors WITHOUT the aid of tools to make
the humans' jobs easier.

See above.  I generally agree with this goal.

My point, as below, was that Waze is another crowd-sourced map which has
much better tools and support for semi-automated editing than OSM does.
What difference does the license make?
