Creatives work on design to be creative; they don't outright steal it to save time and resources. It's what thy do and witness what happens when you cross them.
I think the OP is about copyright infringement and plagiarism, which is a form of fraud. I do not justify it but it is not theft.
I don't think the world has much to benefit from plagiarism, but I think the benefits of copying others' work and building upon them freely far outweigh the downsides.
