Nihilism is a question about meaning, not an answer, so this author starts off in the wrong place by trying to find a meaning - as most do who take the moniker of "Nihilist."

Seems like the author is taking the absurdist/existentialist solution of choosing what is valuable. In this case trying to tie a more complex understanding of individualist hedonism ("feeling" meaning) with some kind of combinatorial pluralistic hedonism.

Pretty simply this is just a more verbose version of the existentialist hedonistic answer to the question of meaninglessness.

To quote the author:

I'm almost certainly reinventing the wheel

Pretty typical really. Most people who truly embrace the absurd either don't seek meaning or have already killed themselves.
