Other than the obvious, self-reflective question that the author doesn't pose - "what if I'm the one who's wrong?" - I think it's worth arguing if the conditions are right.
Because I also like being correct, a debate to me has become something of a game where (ideally) we both win in both end scenarios: either my thinking was correct, and now I verified/validated it, and got you to think differently; or my thinking was incorrect, and you corrected it for me (or helped me get there).
However, I implicitly figured out that there are some qualifiers to actually getting the benefits:
- Can I be, and remain, polite and reflective? If not, my personality or knee-jerk responses will always get in the way of an argument's benefits.
- Is the subject sensitive to the person for whatever reason? If yes, any argument inadvertently becomes a signal of a person's worth.
- Are we in a competitive setting (e.g., corporate meeting, or larger social group)? If yes, any argument inadvertently becomes a social status competition.
- Do I know how to stick to the issue (instead of moving goalposts), and stop when the debate gets overwhelming (too long, too much difference)? If not, I'll overstep the boundary after which it isn't mutually beneficial anymore.
These are not easy to figure out, and sure, maybe stop arguing with most people if the conditions aren't right.
But unless you stop communicating altogether, I don't see how you can stop arguing with people in general.
