We get that you’re trying to somehow translate every counter-argument to “DIS RIPPING PEOPLE OFF”. You haven’t explained why ripping people off is wrong though, especially if both people in a deal are satisfied.
Is it wrong because there is a god in the sky watching over all of us and the economy, selecting people who go to hell based on how much they buy and sell items for relative to god’s self-opinionated market prices?
Or is it wrong because you have the need to loudly voice special snowflake opinions in every thread?
