Ropes, especially those made of synthetic materials, are almost indestructible.
The lifetime of what they connect is usually shorter than of the rope.
Chains rust if they aren’t maintained.
To eventually perish and end up in uselessness.
In some cases it is an advantage, in others not.
Because chains have many different uses.
The same are true for locks.
“Humen rattle their chains-to manifest their freedom“
Arthur Helps – english writer and dean (early animal rights activist)
