Lets compare having a politics forum with the intention manifestion forum (the psychic forum is similar).
There are a lot of readers of Steves material that don't subscribe to the IM concept. If we wouldn't have the IM forum we would have IM threads in Health, Personal Effectiveness, Character & Development, Technology & Technical Skills, Business & Financial, Emotional Mastery and Social & Relationships.
Having the IM forum allows those people who are more interested into "skeptic personal development" to discuss in those forums and ignore the IM board.
Having a politics forum would help you to filter out the political threads that are at the moment in General/Business/Personal Effectiveness/
Character & Contribution and Fun & Recreation

So, maybe we should have also have a forum about cars? Cars impact us, it's central to our lives, and some people on here would love to have a forum on cars to talk about cars.

Topics about cars that are central to our lives like how much the gas should cost or whether you should not buy certain environmentally unfriendly cars would fit in a worldly affairs forum.
In addition I haven't seen much threads that would let me suspect that a lot of people would want to have here discussion about cars.

3) It distracts us from discussing what we can do, to being concerned about what others are doing to us through the government.

7) Encourages people to think in terms of scarcity.

It's unfortunate that you see politics that way but it's your choice.
The perspective of looking at politics purely from the scarcity perspective by seeing the worst in everything is unfortunately quite popular you don't have to take that perspective. I don't.

Just a few controversial topics from the top of my head. I'd say that these, for the most part, are more controversial then the LoA because they emotes more anger and fear in people then the LoA does.

Don't underrate the controversialness of the LoA.

5) It will bring in outside people who don't care about personal development, but only care about pushing their candidate or their opinion on to the rest of us.

I think we should prevent the forum from being able to read from unregistered members to prevent people from joining for the reason to promote there candidate. We might even set a limit of 10 posts that you have to have to post in the forum.
It would also be an option to add an extra user group for the people who want to participate in the forum.
That would give you the option to see fewer political thread than there are at the moment, because the forum would draw all political thread while given the people who want to discuss politics an option to do so.
It would also allow us to make additional (stricter) rules for the forum and simply remove people who misbehave from the group that can participate in the forum.

I think "Politics and other Worldly Affairs" would be a good title for the forum.
