The problem with strategies like that (if they work) is that some crook will likely still trash your car breaking in and trying to start it (as I once discovered... I'd rather have my car stolen and totaled than simply vandalized). Then when they can't start it they'll trash it some more.
I still think it's better to have a visual deterrent or something that indicates you have an anti-theft device. However, I agree clubs are useless. I saw a video once of someone disabling a club in about 10 seconds. If not for all the steering controls I'd suggest rigging up a system to remove the steering wheel altogether. That would work
