Oops, I forgot the endgame and freeing people from the overpass, thanks for the corrections.
Still, for the majority of tele-operated period, there aren't any strong incentives to break it. Robots don't get immobilized by the overpass too often (once every 3-4 games maybe), and the trackball-knocking only happens in the last 20-25 seconds of the match. So when thinking only about points in time when I'm correct, then my statement was right!

On topic, I'm very conflicted about whether this is lawyering or not. The intent of G22 is to promote circular play. Having a string on your robot, while it is definitely using a loophole in the rules, doesn't break the intent of G22, as you'll still be restricted to circular play. However, using a string comes only as a very to-the-letter interpretation of the rule.
