You just named a bunch of things individual Lanterns can do. And dozens, if not hundreds of Lanterns fled in terror when Mogo was authorized to use lethal force on them.
Also, the only way to really take him down is by destroying his core, and the shell around said core is durable enough to where it took black hole powered gravity drills an extended amount of time to burrow through. I don't think being pulled apart will otherwise be a huge deal. When his core destroyed he reconstituted himself, and that hole light speed debris field trick was him basically spitting a continent worth of rocks at the Third Army and then sucking them back into place.
