I agree that establishing the general claim that voting based on current karma harms more than it helps requires more than the first paragraph, and is just a statement of a conclusion rather than an argument leading to that conclusion.
But I think the rest of the second paragraph is related to the first—the reason why it decreases the info content of voting is because the votes are clashing (your vote on a comment is now negatively correlated with my vote, making your vote less influential).
I also don’t think the first claim makes much sense. First of all, it’s not always anti correlated. It’s only anti-correlated if you vote unconditionally, and the post is far below or far above the value we think it provides. If it’s positive, but not positive enough, the vote is correlated. If it’s negative, but not negative enough, the vote is correlated.
Secondly, you’re assuming everyone uses the same scoring rule you do. We’ve already established that at least two people use the different scoring rule, and as another commenter pointed out, it’s likely that there are many people who vote strategically. In that case, if we think the post has the same value, we’d do the same thing in the same situation, and if we think it doesn’t ahve the same value, they’re not—which is how it should be.
I don’t think your second paragraph follows from your first.
