Don' need no steenkin' plans. Plans, for me, are for inspiration, not for guidelines. I very seldom use someone elses plans, and when I do I change what I don't like, which is often most of them. I prefer googling pictures, get inspiration, then make my own plans for whatever. Much more satisfying, and definitely much more fun.
I do know a few people, who are very qualified to draw up their own plans, in minute detail, but instead work from other peoples plans. However, they are using the plans for making model historic ships, not general woodworking. As I said, they are perfectly capable of making their own plans for them, but it is time consuming, with a whole lot of research. So, for them, it just makes sense for them to follow plans done by someone else. Me, I'd probably still make a change or two.

.....Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
