I don’t comment more because writing comments takes time. I think that in person discussions tend to add more value per minute. (I expect your post is targeted at people who comment less than I do, but the reasons may be similar.)
I can imagine getting more mileage out of quick comments, which would necessarily be short and unplished. I’m less likely to do that because I feel like fast comments will often reflect poorly on me for a variety of reasons: they would have frequent and sometimes consequential errors (that would be excused in a short in-person discussion because of time), in general hastily-written comments send negative signal (better people write better comments, faster comments are worse, full model left as exercise for reader), I’d frequently leave errors uncorrected or threads of conversation dropped, and so on.
