There are clearly other ways to solve this that don't involve depriving people of food stamps. Most every other developed country has figured out some solution.

First of all, in most countries an expired proof of citizenship is accepted for many purposes because it's assumed that people didn't go out of their way to coincidentally lose their citizenship or permanent residence when the ID expired. If it proves residence or driving qualifications, then there are certainly other reasons why it should expire.

Suppose we have an administration, decentralized or otherwise, that stores the records of the people concerned. They can then be contacted and details can be verified.

This informal verification already occurs on many levels, particularly in the US due to the lack of consistent ID. Try flying on a flight without photo ID, entering the US as a US citizen without proof of citizenship, etc. You will be permitted to do so with a bit of extra hassle while you're identified to a reasonable degree of confidence.
