"The flaw in your example is "you TOOK someone's piece of marble." You
may have added value to the marble FOR THE OWNER, if he likes your
statue. Or, you may have REDUCED it's value to the owner, if he
intended to use the marble for a counter top. The point being, that you
cannot base "increased value" arguments when you base your premise on
STEALING the item in the first place."
This is not a flaw - this is the main point of the example.
It shows that property right is not given by creation. The fact that
it was *you* who wrote the book does not give you any property rights
over the copy of the book someone else bought. He now owns it. The
fact that you wrote the story does not now give you any property right in it.
"In other words, he thinks it would be fine for others to demand
that YOU do one hour of work for them a day for free, and that is
acceptable until more than 24 people have made that same demand."
Oh really? Can I have a quote?
