Voter ID: Who favors it, and why?

I can only speak for myself on this issue and this is what my argument comes down to:

Besides the physical act of voting, what other action can any human perform which is of greater consequence for your future, your family's future, your neighbor's future, your community's future, your city's future, your state's future and your nation's future?

With your vote being such a powerfully and uniquely consequential act, why should you not have to prove you are the one and only human on the planet allowed to cast a vote in your name for who/whatever candidate, proposition, initiative, judge, etc. you alone feel is most beneficial for you, your family, your neighborhood, your city, your state and/or your nation? How better to prove you are you than presenting a valid state-issued photo ID at a polling station? This deeply personal and consequential decision could have repercussions for many years, decades/lifetime even, so why should this most obvious of obvious reasons be debated?

On a wider scale, Gallup conducted a 2016 poll on voting preferences (early voting, ID requirements and automatic voter registration) and the results certainly speak volumes:

I was focusing on the photo ID requirement angle in this post and even large majorities of Democrats and non-whites favor this sensible action but an important question posed by Gallup dealt with early voting. In my research, I found as many as 13 states either do not allow early voting at all or only allow valid in-person absentee excuses for early voting. What I find most interesting about this is the fury unleashed by Democrats against states who do allow early voting but decide to reduce either the number of early voting locations, number of days to early vote and/or the times of day a given early polling location is left open. Normally, the excuses given for any of these adjustments is financially driven but said fury is directed at accusations of voter suppression and all the other usual complaints by Democrats. My point is this: where is the fury against the 13 states which only allow specific reasons for voting early or, more importantly, do not allow any early voting whatsoever?

Here is a video I like to share with anybody who believes blacks cannot be allowed to be inconvenienced under the guise of voter suppression:
