That does not make sense. What does “harm” mean to you?
Less good is not “potential harm”. To put it another way, let’s assume you and I are completely independent and I have to moral responsibility to give you money. If I chose to not give you any money, you would not be harmed. If I gifted you $100, you would not be harmed. If I gifted you $20 you would not be harmed because I did not gift you $100.
