You act like it's blatantly obvious that commodities would exist under communism and mock the person who pointed it out to you, yet you vehemently deny that something else just as obvious as the existence of commodities will also still very much exist and have a place under communism, calling it utter nonsense and requiring "bourgeois philosophy" without any explanation. That something else involves sex, though. Hmm. Funny how work that involves sex always brings out a specific type with an angry and reactionary axe to grind.
At least u/porcupine can make a reasonable case by redefining prostitution as something other than and separate from sex work rather than denying the legitimacy and validity of sex work.
