Then your only example of how it is better has nothing to do with 
namespaces and I already gave some examples (which David also agreed 
with) where readability is actually hampered. I.e. its not so black and 
white.

Nobody is saying namespaces are evil; its all a matter of weighing the 
good and the bad.  And if you overuse namespaces (i.e have more then one 
namespace for any library) then the small amount of good points that 
namespaces bring will quickly be overshadowed by the readability, 
learnability and feeling of having an overdesigned API.
