Well, that is just wrong.

"By all estimates, those least likely to have a government-issued photo ID fall into one of four categories: the elderly, minorities, the poor and young adults aged 18 to 24. The Brennan Center estimates that 1
8 percent of all seniors and 25 percent of African-Americans don't have picture IDs."

"Many people have multiple forms of identification, including those that display their pictures — like employee badges or credit and debit cards. But states with strict voter ID laws require people to have certain photo IDs issued by governments. That typically means driver's licenses.
But many seniors and many poor people don't drive. In big cities, many minorities rely on public transit. And many young adults, especially those in college, don't yet have licenses.
A good number of these people, particularly seniors, function well with the IDs they have long had — such as Medicaid cards, Social Security cards or bank cards. Among the elderly, many of them have banked at the same branch for so long that tellers recognize them without needing to see their IDs. They also may rarely need to cash or deposit checks, relying instead on the direct depositing of Social Security and pension payments."

"In most states with voter ID laws, citizens must present birth certificates to obtain new photo IDs. Seniors and those born in rural areas, in particular, face a difficult time meeting the requirement because birth certificates weren't regularly generated in the 1930s and earlier. And many of these people were delivered by midwives, who often improperly spelled babies' and parents' names on birth documents.
People are caught in a Catch-22: You need a birth certificate to get this ID, but to get a birth certificate you have to have an ID. If a state does have a person's birth certificate, they often must present a photo ID to obtain a copy. That can put an individual back at square one, says Elisabeth MacNamara, who heads the League of Women Voters."

It may be that you have the time, the energy, and the paperwork to easily get a government-issued photo ID, That doesn't mean it is the case for everyone else.
And the purpose of photo ID at the polling place is to fix a non-existent problem--voter impersonation. It simply doesn't happen, for the reasons I discussed above.
