This is an interesting topic that I hadn’t heard discussed before, and I appreciate learning about these benefits!
While I understand that your goal here was to list arguments in favor of competitive debate, and leave any counterarguments out of the scope, I also think that in doing so you might have fallen short of the stated promise to
do so in the spirit of anti-debate – pointing out the limitations of my arguments where I notice them, and leaving open the possibility that anti-debate could be a superior alternative.
Overall, I think that this aim is incompatible with your decision that
[the disadvantages of competitive debate] – and therefore any all-things-considered conclusions – fall outside of the scope of this post.
unless you plan to write further posts following up on those disadvantages.
In particular, it seems like this post naturally raises the question “and what are the negative impacts of competitive debate on the debaters, if any?”, to which it seems like there are some obvious answers, and probably some less obvious ones.
I think that listing benefits on its own is a fine basis for a post; it just doesn’t seem to me like “the spirit of anti-debate”.

I haven’t read Lukas Gloor’s post, so I’m not sure whether this counts as “subjectivism” and therefore is implausible to you, but:
Another way to end up with reliable moral beliefs would be if they do provide an evolutionary benefit. There might be objective facts about exactly which moral systems provide this benefit, and believing in a useful moral system could help you to enact that moral system.
For example, it could be the case that what is “good” is what benefits your genes without benefiting you personally. People could thus correctly believe that there are some actions that are good, in the same way they believe that some actions are “helpful”. I think, and have been told, that there are mathematical reasons to think this particular instantiation is not the case, but I haven’t fully understood them yet.
