You are making taking the small cost for getting a drivers license, or state ID of any kind and conflating that as being the cost of voting, which is just unreasonable.

If you really want to get nitpicky like that, we can bring up implicit costs and opportunity costs too.

It takes time and energy to physically travel to voting stations to even cast your vote--an opportunity cost.

It might take some people 1.50$ in change to pay the bus fare to travel to the voting station and perhaps an hour of their time.

Meanwhile, others who may not have cars during election season (like myself at the time) may opt to pay for a 10$ uber to get to the polling station and get there in 12 minutes, because it's much faster.

Then there are those who did have vehicles at the time and would have gotten to the voting station in 6 minutes but in doing so, let's say they had to spend say 3$ worth of gas to get to and from the location.

Point being, is that life ALWAYS has costs for doing things. Whether it is an explicit financial cost, or if it's an implicit opportunity cost of time and energy.

And thus it is unrealistic to claim that voter ID requirements are injust because minorities take on a much bigger burden in acquiring identification than those middle class households for whom 15$ represents a much smaller fraction of their annual income.

It all comes down to how much it's worth to each individual to ensure they cast their vote.

Additionally of course, as pertaining to Identification, it is up to us as a collective to decide whether the costs associated with implementing this as a voter requirement, is worth being able to ensure our elections are more secure and fraudulent votes are much more difficult to be submitted.

If a minority person has somehow gone their entire adult lives somehow never acquiring a form of identification, and they claim they care enough about our country to vote, yet they genuinely feel the time and effort needed to travel to the nearest DMV, and pay the 15-20$ cost for acquiring a state ID, is too great of a cost for them to bear, then they likely do not actually care enough about our country to be voting anyway.

The barrier to entry for voting is so small. Anyone who actually cares about securing honest elections in this country would not be incentivized to sacrifice the security and integrity of our elections, in hopes of making the barrier to entry for voting even smaller than it already is.
