The addition of consenting actors does not make the “production”/sex act performed for an exchange of money or services an ethical product. The objectification/commodification of human in such a capacity is unethical without even going into the coerciveness of the industry/society in a financial downfall.
Fictional or not, your partner or a stranger, it does not matter. You are reducing them down to nothing more than parts/functions related to parts. It conditions society to without realizing it begin to develop a less humane approach to a persons value by equating it to something so simple and carnal as lust for lust and/or lust for profit. This isnt even getting into the addictive nature of it for the viewer and so forth. Pornography is an immoral product.
Furthermore, unlike other forms of labor that tend to produce a product; sex if successful from a biological perspective creates additional life. So if sex is not done for that purpose, and also not for intimacy, then doing it for money reduces the human body itself to being a product rather than a person being paid for something such as food, or entertainment, or for some act of tangible value. (not porn , porn is not entertainment but thats another take) porn is produced for money and/for
Carnal fulfillment that is not beneficial to anybody or the biological act it primarily is used for (procreation) so being reduced to either being produced for money or to satiate somebodys horniness instead of having actual intimacy reduces the human once again into a commodity and not a living breathing sentient intelligent creature with a full range of emotions, thought processes, etc.
