"…I think vibrations of low frequency are not as damaging…as vibrations of high frequency"

You obviously either don't have a turntable and below 20 Hz vibration in the system or you're using a "rumble filter" or your speakers roll off significantly by 20 Hz.

Low frequency vibration can be a very big problem under some circumstances and magnifying it makes it a bigger problem.

Actually I believe that if you could do an A/B type comparison between a system set up with good low frequency isolation and the same system without, you'd probably notice a difference and prefer to have the isolation. The problem with some things like vibration control is that you only start to notice the damage that gets done to the sound by vibration when you hear the sound with less vibration. The reason you don't notice it before then is that it's always there as part of the sound, you're used to it and you don't have any reason to expect things to be able to sound different. It's only once you hear the sound without the contribution that vibration makes that you realise how much effect it was having.
