I agree that it's best to learn texturing "the hard way," and I also agree that the results of "merchant resource kits" tend to be bland and and lower-quality, but limiting sales of any creative resource is likely to breed serious resentment. It's bad enough that in our community some people take on a regal attitude when they become a "merchant." :-) Interestingly, the most talented seem not to do that. I can't think of friendlier and more open folks than Stonemason and face_off, for example. I know you're referring to character mesh textures, but if all resource kits were limited to merchants only, non-merchants like myself wouldn't be able to buy resources for noncommercial use. I've purchased several texture tile packs for my own texture creations. I've given some away but am not interested in selling them.
