I'll comment more later, as it is definitely at the end of my day.
But I feel the need to point out that it is not "impossible" to place
copyrighted material in the public domain in the US and that there
are definite and relatively clear arguments that one can do this
under US law.
I'd also like to mention that I'm not really sure how accurate it is
to say that there are many countries with "no concept of the public
domain", as no one has perpetual copyright and the public domain in
this sense is "out of copyright". Everything more or less expires at
There are however systems that enforce *moral rights indefinitely,
but this is distinct from the economic rights of copyright.
This is all not to say that your ultimate point that creating public
domain data may be hard isn't true. Truly giving up all the copyright
to a copyrightable work may be impossible in some systems. However
the Open Data Commons Public Domain Dedication and Licence (PDDL) has
a back up licence in place (like a BSD/MIT licence without any
restrictions) to try to address these situations.
Estoppel would then also operate to bar people from making claims
against end users after placing their work under the PDDL.
