It is commonly accepted that some things, such as sex, organs, secrets, and votes may be given away, used or owned, but not bought and sold. I refer to markets such as these as 'contested markets'. The commodification debate asks whether these markets are impermissible. Specifically, the commodification debate asks what is morally permissible to buy and sell, and what is legally permissible to buy and sell. One position within the commodification debate is that of universal commodification. This position holds that all contested markets are permissible. However, this position is wrong. Ultimately, falsely presuming that contested markets are permissible can lead to important questions about permissibility being eschewed, and wrongful markets being implemented. Two arguments supporting universal commodification are Jason Brennan and Peter M. Jaworski's defense of the principle 'Markets Without Limits', and Tait Szabo's defense of the 'gift-commodity principle'. Markets Without Limits makes a claim about what is morally permissible and states that: “If you may do it for free, then you may do it for money.”1 The gift-commodity principle makes a claim about what is legally permissible and states that: “[…] if it is (or ought to be) legally permissible for me to give away or not give away X, then it ought to be legally permissible for me to sell X.”2 My thesis will reject universal commodification, both as applied to moral permissibility and legal permissibility. Specifically, I will reject Markets Without limits and the gift-commodity principle on Brennan and Jaworski's and Szabo's own premises by showing that transactions in the content of democratic votes are morally impermissible, and that blackmail ought to be prohibited. By rejecting universal commodification as applied to both moral and legal permissibility, I provide a comprehensive rejection of the position. I complement the existing criticism by providing a comprehensive rejection of universal commodification, especially on proponents of the position's own premises.
