Matteo Bechini I'm sorry, I don't follow what you're saying.  There is nothing preventing anyone from selling public domain works. Go into any book store and look for works by William Shakespeare; I guarantee the will ask you to pay for a copy of any or all of his public domain plays.  

But creators trying to make a living aren't usually advised to dedicate their work to the public domain (with CC0 or similar).  I use CC0 for public service stuff that I want to share.

It seems to me donations and crowd fu
nding are far more suited to CC than © all rights reserved.  Why on earth would I donate money to someone who is just going to create locked down work?  I've spent my life paying for copyright works that I can't use for anything but passive watching.
