Why do you want it?
You can report comments by flagging them or in egregious cases by emailing hn@ycombinator.com.

Clearly I don't care that much, which is why it took me 10 years to ask the question... I know it's just internet points, etc etc. I guess when I see someone saying something that I absolutely know is objectively wrong, I would like to show my disapproval without sitting down and actually fleshing out a response. I'm not the best at putting my thoughts into keystrokes (this little response took me a good 30 minutes to write).
Also (sidenote) I don't love how I had to scroll through a bunch of comments to find this response, or even to know that you responded to me. I wish there was some "notification" or something that let me know that you cared enough to take the time to reply to my comment.
I think this is exactly the reason why there is a limit. That downvote wouldn't contribute to the discussion whereas your fleshed out response would.
Also, if I recall correctly, when you downvote you're supposed to explain why.
And ofc up and down votes should indicate contributions to discussion. Meaning that if something is incorrect or you don't agree with it, doesn't necessarily mean that it should be downvoted.
I mean no disrespect in this follow-up question, but given how little you've participated in this community's discourse, do you still feel like you've earned that anonymous and concrete voice of disapproval?
I mean "concrete" here in that a downvote can actually help bury/remove a comment, and so you have actual power to influence this community when you have that ability.
Edit: to your "note" about finding replies, if go to your profile, you can view a list of all your comments, along with replies to them. It's not great but it's easier than scrolling a whole comments section.
You can also use something like "HN Enhancement Suite", a browser plugin that improves the overall UI of Hacker News (although I think you said you mostly browse on a phone so that won't help you there).
I think the conventionally accepted stats for mainstream social media is that 10% of the users account for 80% of the content, or something similar to that?
I don't know if HN has ever published these kinds of stats but it would be interesting to see.
People downvoting for simple disagreements will create groupthink, and we loose the opportunity for having interesting discussions.
I suspect most downvotes come from disagreements, but there is no way to verify that.
There's no real point in having rules you can't enforce anyway. If you wanted to stop that you would have to get rid of downvotes alltogether.
I used to think downvotes were a good thing and I wished some other forums had them, but HNs downvote system changed my mind. I wonder if that would increase the load on the mods because then people would use flagging for that? I don't know. It's not my forum, I don't have access to the statistics and I don't get a say anyway!
