ID in the us is a huge pita. There no reason to require it for voting anyway, fraud isn't a real problem. it's just a good way to prevent poor people from voting.

> cash a check
You can sign it over to someone else and have them cash it. Also many employers (especially in poor areas) offer paychecks on a prepaid card. No check necessary.
> apply for government benefits
You can often do this with lesser IDs such as a birth certificate or school ID, which are often not accepted at the polls.
> buy cold medication
Poor people don't buy much cold medication.
> board an airplane
Poor people don't board many airplanes.
> open a bank account
Poor people are notoriously underbanked, and often don't trust banks anyway (especially since banks have a bad habit of targeting the poorest customers with the highest fees).
Why the US refuses to do either of those things, instead putting a lot of hassle on the population when election participation is so low it jeopardizes the fundamentals of democracy, that people feel like the government actually represents them, I have no idea.
If people were voting under other people's names in significant numbers, it'd be obvious when the real voters came in and found out they were already marked. That very seldom happens.
The reason people don't do it is probably that an extra vote or two is unlikely to make any difference, so the risk/reward is poor. It's hard enough getting people to take the time to vote in the first place, much less risk a felony conviction to vote more than once.
IIRC a number of countries use an indelible ink pad that voters have to place a finger on.
"BUT ITS NOT A HUGE PROBLEM"
it still happens, which is a problem none-the-less.
