I believe the idea is that the "wrongness" of stealing is based on some moral principle, not on whether or not people and the legal system consider it wrong. Many people who believe firmly in property rights believe them to be moral rights, not rights in the sense of legislatively granted rights (rights created by the collective). It's hence not necessarily moral dissonance. It's quite possible for someone to believe that property rights are 'natural rights', ergo stealing is wrong, but not believe people have any rights to things they didn't acquire by work or exchange, hence not view 'dispossession' as wrong.
