While most rationalists would happily and quickly plan [...], anecdotally many seem hesitant or even hostile to the idea of using fashion as a tool to achieve their objectives.

This point is essentially the point of having your article here on LW, but it is not emphasized strongly enough, in my opinion.

Additionally, I think the point that "the tool of fashion is one you are using to convey some information, whether you intend a message or not" is an essential point that I did not see in your text.
