Full Idea
If I repair or destroy an item, I do not repair or destroy each part of it (and since each part of a part is a part this would be difficult).

A Reaction
This seems like a nice refutation of any attempt to claim that a thing is no more than the sum of its parts, but one could analyse the notion of 'destroy', and find it just meant introducing gaps between parts.
