The standard reason for not pirating is that it cost the producers money. In the case where they won't sell it at prices (some) people would pay for, who does piracy hurt?
I don't see "they won't sell it to me at a price I like" as justification for pirating it yourself as if it's somehow deserved. I would much prefer people use an argument not based on whether or not the cost means you should be allowed to have it or not.
