I recognise you are trying to explain that variance in return is less with pooled mining or higher hashrate, but this is meaningful only because humans think that way because of our weird broken minds. That is, a lower variance in return, and especially a more-frequent payout, feels like it is worth more to humans just because we all know we might get hit by a bus tomorrow.
Indeed, I believe a big proportion of people are indeed risk-seeking (enjoys taking risk).
Just see how many people go to Vegas or gambling sites to play those negative EV games.
