Not planets, asteroids. Will Belters be able to refine and create high tech alloys in zero g? Will they be able to manufacture parts and equipment in zero g, at scale. It may be that all those activities require gravity, or are exceedingly difficult in zero g, we don't know. In the case that those things are hard in zero g, my proposition is that Mars will be desirable place for those activities due to its low gravity and atm making it easy to send back up.
