It's rather a metaphor for life: a slightly random jumble of maybe-useful stuff that somehow fits in between birth and death. Over-tidiness simply means you could have been getting on with fun stuff rather than rearranging your cupboards yet again with stuff you rarely use anyway.
My parents had a lovely bone china tea set they were given for a wedding present, but it stayed in the cupboard, virtually unused, for the 60 years they were in the house, as it was deemed to nice and too delicate to use.
