Yes, that's an advantage I've used quite a lot.

Like most "Danger!" warnings, I think that one is overblown. The hacker 
would have to observe a clean fingerprint, would have to know it's from 
the proper finger, then go though a multi-step process (Photograph, 
process in Photoshop, 3-d print on acetate, re-cast using wood glue) to 
get something that might work, might not work.

I can see the fictional characters in "Mission Impossible" doing it to 
thwart an evil genius preparing for world domination. I doubt anyone 
would be using it in real life to access my medical records.
