Thanks; this comment made me happy. Part of the answer is that I generally have low self-esteem, which negatively affects my perception of the quality of certain things that I have written. Another part of the answer was that I wrote this with the very specific goal of estimating values of the "years of life added vs. age at castration" curve at different points in mind, which seems much more narrow than the goal of doing basic science work, which is most of what journals publish.

Additionally, many journals have publication fees, which I would have to pay out of pocket. Others charge readers access fees; I'd rather people be able to access my work freely. As things currently stand, I might still be able to mention this work during interviews as an example of a time when I noticed others didn't seem to be working on a certain problem and took action myself, if the interviewer didn't seem to be prejudiced against transhumanist or LGBT folks.
