I don't have a problem with "LARP" as I understood the analogy and having a bit of flair in writing helps make it memorable. Editorially speaking it may be too niche a reference and be confusing. (Reading these comments it certainly has been.)

The condescension I see is in calling out "technologists." I've never heard that before. Just looking at the word it sounds like it means a person who works with modern technology. Wouldn't that encompass the majority of Hacker News readers? But by context you don't seem to have a favorable opinion of the group. What makes someone a technologist to you? Do you include yourself and if not why not? What justification is there for you to generalize people in such an unflattering way?
