He that hath no money needeth no purse.

A person without money has no need for something designed to carry or protect money. The saying points out that a useful possession becomes unnecessary when the thing it serves is absent.

It can also express a dry, practical observation about lack: when someone lacks the underlying resource, related expenses, accessories, or safeguards may be irrelevant.

Use it as an ironic or matter-of-fact comment when someone lacks the resource that would make an associated item useful.
