First, do we not have proof of identity? How often should we have proof of idenity? How many cases of fraud are there per year? How large is the problem?
Second, who should issue a different proof of identity? How much should it cost? Should the requirements be left to states or the federal government?
Third, who would administer this system. Would it be public or private, or left to states? What criminal and civil law should exist for misusing this law for witholding the right to vote on this basis? Would you trust a non-Republican leadership if DHS still was the agency verifying identity documents and storing soft-copies of them?
What you want isn't unreasonable, but you leave out so many details that your reasonable statement can be misused for ill intent and denying people their right to vote.
A fair follow up question for me to you might be "how do you feel about the additional requirements for married women to get reissued vital documents when they have changed their birth name to their husband's last name in the SAVE act?" When concerns like these aren't addressed in massive changes to voting laws, it makes lots of people uncomfortable that the changes aren't made in good faith.
