I'm not gonna get into the argument of whether tattoos are good or bad or evil or great or what, because one side of that argument is wrong
Instead I'm going to say that Mr. Holloway's idea of a morph-able one shot "thousands of needles stabbing you at once" idea is downright torture. A tattoo hurts. A gun stabbing you several times at once (no one does single needle work...) hurts. After a while, your body goes numb to the pain. after a while longer, your body fatigues from the pain (ask the doctors here). 3 or 4 hours of constant tattooing is the limit, you actually start to damage systems after that (long term trauma).
A complete tattoo at once? you'd have people passing out left and right, especially if it was more than a tiny flower.
