You are not wrong.

Still there is always the question, why at this digital age do we need to do things physically?

Using that question socialists will push a digital id.

You (and I) might not like non in person voting but right now the US is stubbornly allowing Mail voting. When the criticizers will point out to how unsecure that is, the socialists will pull out digital IDs.

The best way to go, is to prevent digital IDs. The second best is to offer a privacy respecting alternative.
