In what way is the world a better place when you have to reimplement the design from scratch - as opposed to a world where anyone can copy a design (assuming some credit is given)? Sounds like the latter world will free up a lot of resources for more useful creative work.
Because of the fundamental concept of property, and ownership, and the right to control your own creations? It's one thing to voluntarily release something into the public domain (or enable its direct re-use via licenses like Creative Commons). It's another thing to say that all work should be public property, usable as long as credit is given. Or are you suggesting that everything belongs to the People, comrade? Eve…
Yes, the WBC should be allowed to copy if everyone else is.
The benefits seem to me to dwarf the downsides.
