Although it has to be said, that if you have say a commercial kitchen, and you re establish a zone of protection by bonding extraneous conductive parts back to the earth terminal on the kitchen DB (which is local to the kitchen) you will substantially reduce touch voltages - the basis physics says so.
That doesn't mean bonding the legs of moveable tables and the like, I agree - but as a principle re establishing that zone of protection is no bad thing
