tonedeaf, it is exactly as you say:
> Most people loop their cables somehow around the stand or just tape the cables to the stand to allow for the slack loop.
The point which John W. and I are trying to make here is that this can be done well or it can be done poorly, and that the difference matters.
Think of airports these days--they have "sterile" areas in which everyone present has definitely gone through a security check, and public areas which anyone can get into. The transition from one type of zone to the other is handled in very particular ways. A microphone stand is physically coupled to the floor, while the cradle of the shock mount is physically coupled to the microphone body. Particularly when directional microphones are used, it's vital to prevent vibrations from being conducted from the stand to the microphone body.
Shock mounts aren't magical objects that cancel vibration just by having the microphone touch them; they're effective only if they're designed correctly and used correctly. I have high respect for China as a nation and for Chinese people, but all the cheap Chinese shock mounts I've seen suck totally, and have little relation to what a shock mount is supposed to do. It's no wonder people don't bother using them correctly; with such shoddy design and build quality, it doesn't make much difference how they are or aren't used.
Good shock mounts on the other hand can make a real difference if used correctly. They are the products of real engineering design and careful production. Thus they can't be made for the price of a pack of Kleenex--but as John's Rycote examples show well, they don't have to cost too much. Likewise with the Shure "rubber donut"--as long as some way of tying off the cables is arranged, they can work very well and they don't cost hundreds of dollars either.
