I can find tons of people who can drawn and make music.
I don't know even a single person who could translate Finnish to, idk, Welsh. Ik those people exist, but there is about 50-200 in the world. Of 8 billion people.
You're definitely not taking someone's job or stealing IP when translating, and the model doesn't need to have been fed any stolen art. It doesn't need to be conversational, it just needs to translate text roughly.
