say I start charging you 40 USD for clothes you have bought from someone else, you are washing yourself, reparing, and other people made, using their own tools and materials. I did close to nothing, and yet "you will be wearing it for a year". great, but that does not mean there is no ripoff from my part. I have close to nothing to do with your clothes, even if they are obviously useful to you for next year.

same story here. marginal contribution is too low compared to price
