A version of 2 minimally. [the factor of choice on the
  moment-by-moment level, but within a LARGE amount of constraints
  which COULD make free will statistically a 0, but I don't round
  myself). a version of 4 but not as an ontological condition but
  relativistic and highly conditional to perspective. For 1, I'm
  agnostic. For 3? The highest I expect is relief of discomfort,
  which some people interpret as pleasure. Giddiness (which some
  people interpret as happiness) is a form of masked pain to me.
  Statistically 5 but I'm not rounding up to it. I live in the
  ever closing statistical gap between near-certainty and
  certainty never reaching certainty.   == I don't fear that
  antinatalists could be right. It doesn't matter to me if
  antinataliists are right or wrong. I'm not looking for universal
  solutions for all of humanity. == You nailed it. I expect
  failure and I'm fine with failure. But I give things a shot. I
  have various criteria. Sometimes it' boredom. I use boredom as a
  clue to stop working on something. It's a sign that maybe I'm
  bored because I did everything I could do about it, and can find
  no more to do about it. Sometimes I ask myself "what am I
  avoiding?" That sometimes gets projects restarted. But I usually
  stop at "good enough". I'm not looking to impress anybody else,
  not really. [it's nice to get a 'like' and a like emoticon of
  course but it doesn't matter]. I produce stuff. Stuff comes out
  of my head 'cause there's not much room in there. How people
  perceive it? Well it'd be nice if they like it. If they don't?
  They don't. I don't hate them for it. They gotta live in
  themselves. I gotta live in mine. == I'm annoying to logical
  people sometimes. I slide around fallacies on a regular basis.
  It's a hobby, a curse and probably just my personality. I'm a
  contrarian who is contrarian about even that sometimes.. ==
