My initial gut reaction is to agree with you that it might kill creativity.
But then when I think about the tools I use to scratch-build my Fett, I realize they help me make all kinds of short cuts that others might not have access to and certainly not a long time ago. Everything from the ruler I use to make straight lines and X-acto cuts, to the belt sander for shaping to the spray paint (as opposed to brush-applied) are small advances in technology and convenience that I'm comfortable with.
My first Fett when I was 12 was even more scratch-built, using a few magazine pics and my own imagination. So fast forward 36 years and I used templates, reference images and advice from this site, as well as some cast and handmade parts from other TDH members and I wonder if that's killed my creativity? I honestly don't think so.
