I hope not, because that would first of all contradict the whole idea of scientific work. Of course, he/she may not just COPY your paper and distribute under another condition (price!). He/she is not allowed to do this. The reason is first of all a scientific one: he os not allowed to "sell" your ideas as it would be his/her own.
Actually, he *is* allowed to sell it (though not pretending it's his own work), just like distributors may sell GPL software, e.g.

AFAIK local laws overrule the licence of the author.
I'd think so, i.e. if the citation is in a form that is normally allowed (even from proprietary sources), the FDL can't impose any further conditions.
Of course, if you're the only author and rights holder of the FDL text, you can always give someone permission to use it in a particular way since you're not bound by your own license (and if there was a violation, you're the only one who could take action, anyway).
IANAL.
