When media is sold for more money than you make in a month, or is otherwise financially out-of-reach, piracy is ethical (they would have never gotten your sale anyway)

When media is no longer available for sale or pulled from the market, piracy is ethical (there is literally no way to pay the creators)

When media you had legit access to is now unavailable because your account got stolen or you are otherwise locked out of some required online service, piracy is ethical (they won't do business with you)

When media requires something that was stolen from you, lost, or otherwise destroyed, piracy is ethical (you already paid for it)

When media uses DRM, piracy is ethical (doctrine of first sale stipulates you cannot control something after you have sold it, and one should not recognize any "license" for which have custody of the physical bits)
