I don't think photo ID's are an effective certificate for proving identity. So why are we even talking about them? Photo IDs are the solution being discussed here, not some theoretical has-yet-to-be-invented technology that is indistinguishable from magic. You wrote why do we keep excusing people from having a basic mechanism to prove who they say they are? in the context of a mechanism that doesn't do that...so what exactly is the point of introducing a very costly "solution" to a non-existent problem that doesn't actually solve anything?
