Actually, distribution and COPY (i.e., reproduction) rights are at the heart of copyright law.

She has every right to control distribution of her works.

Do not confuse the copyrightability of ideas with the copyrightability of an expression.

IDEA = boy goes to a school for child wizards EXPRESSION = harry potter (a specific example of the idea)
