I know it's like it is for some reason, but on Gaming we get a lot of new users that post comments as answers because they have 1 rep.
Is it possible to lower the rep requirement for commenting to 1 rep?
What is the official reason for it being 50?

We funnel users to the answer input box for a reason -- because the focus is on getting answers to questions, not meta-commentary. Commenting is a privilege that should be earned by providing useful answers. And 50 rep isn't much.
It's highly unlikely a random drive-by user will
So by the time they earn 50 rep, they should have learned roughly how things work, and be in a position to offer a useful comment and not a "+1 AWESOME ANSWER" or "NO U R WRONG!!" sort of comment.
Answers are, in some ways, harder to clean up than comments as they have no utility outside of moderator intervention to remove quickly. Comments can be flagged because one of the flag reasons is noise; there is no equal option for answers. There's also that whole thing where every time a new user posts a comment-as-answer... there's often a very unwelcoming surge of downvotes that follow it.
However, answers are a lot more visible to receive that clean up. Posting an answer bumps it to the front page. There is also the "new posts by new users" list which helps identify these very comment-as-answer posts. Comparatively, there is no real method to monitor for comments apart from manually opening every post or every user's activity logs. If a comment is placed on a really old post, then it can remain unseen for a very long time. Multiply that by a lot to see how problematic it can become when that's granted to everyone.
That's speculation, of course; we don't have exactly proof that this is opening some floodgate and I don't even think it'll turn that bad. But I think it would still be wiser that we have some method conducive to policing and monitoring comments better before we reduce the threshold.
The main point of the sites is to provide answers. If you don't have anything to say that answers the question it's not all that important that you post it.
New users need some time to learn that answers are the central point, not chatting in comments. The hope is they realize that "thank you" doesn't answer the question and therefore don't post it. Having comments available as an obvious place to post such valueless remarks can only increase their amount, not helping anybody.
The reason there is a threshold for comments, is to prevent spammy comments.
