Thats easy, I'd just pay cash or barter for everything or go without. You'd be surprised at the discount rates you can get if you pay cash, expecially for dentists. If something bad happens I'll just go to the nearest emergency room and the taxpayers will pay for my treatment and recovery.I challenge you to get a legal job, open a bank account, cash a check, take out a library book, get a fishing license, register a vehicle or go to a doctor's office for an appointment without ID.
We already have a national ID, it's called a social security number. So why isn't that good enough especially if commiting voter fraud or lying is already a federal offense and punisable with a lengthy prison sentence?And the impact of any of these is miniscule in comparison to voting for the person who is going to run this country.
Being poor or low income does NOT prevent you from obtaining an ID. Most areas/Dept of Human Services even provide some sort of free transportation services for the low income/elderly to the destination of their choice.
