I don't think so. I think you tell them that you don't respect copyright monopolies. That's very different. There can be all sorts of reasons for not respecting copyright, and being unwilling or unable to pay for authorized copies can be one reason, but if the copyright industry assumed that this was the only reason, why would they go to any efforts to stop it?
I think far more prevalent reasons for sharing when it is illegal to do so, as well as downloading such unauthorized copies, are convenience and altruism.
