Didn't you suggest the ceilings thing yourself? But now you're trying to claim it's all or nothing?
Is the problem that it's easy to abuse or that we don't see this particular hypothetical in the movies? Because you seem to be varying between these.
You want a fix for the damage problem? Your fix is a particular houserule that I've seen several times on these forums: "Dealing damage with Move requires the Control upgrade that lets you hurl objects, and does damage equivalently."
You want a fix for the problem of it not fitting the kind of game you want to play? Talk to your hypothetical player. Tell them that you don't want this in your campaign. Simple as that.
At its core, this situation depends on both bad playing and bad GMing to become any kind of serious problem. Decide what's best for your game and do that—I can't change the rules to suit you, and I can't give any concrete advice on a problem player that doesn't actually exist.
We've long reached the point where it's obvious that you don't like the RAW and need either a houserule or a chat with your players. With that in mind, I'm done with this thread; there's no point to continuing when there's nowhere to continue to.
