Earlier quoted context omitted.
You also need to wear clothes and shoes into the polling station. Are those expenses considered poll taxes as well? Straw man, but requiring ID is not really a direct poll tax. I certainly don't feel like I'm being unreasonably taxed when I vote with my ID.
You are thinking of this as a person who already has a government issued ID. If you don't drive and don't travel internationally there isn't much in life that would require you go acquire a government issued ID. If the only reason you need the ID is to vote, many people who don't already have an ID won't vote.
