The point missing in the article is that, in order to enter the US, one needs to give the US Govt their photo and fingerprints ("biometric data") anyway.
There are two options: visa-free with the biometric data passing on the wire (no hassle), or visa (a major hassle) and biometric data passing in the airport (a minor one).
As a side note, the EU also collects photo and fingerprints from visitors now. Whereas in the US you only need to go through fingerprinting only once (or maybe "once per passport") and only on arrival, in the EU you need to go through it both on every arrival and every departure.
