"But the government can already do all that without Digital ID."
That may be true, but the point is that it makes law enforcement less perfect, and that can be good. That is the point "stavros" is making.
Rosa parks broke the law by seating on a seat where she was "not supposed to". Hypothetically, if there were a quick ID check machine on the bus, it could have just prevented the whole thing from happening at all.
There was a "quick check", just not the one based on identity. You can always publicly disagree with the result of the id check too.
