I think it's more about what I believe the target market is for Starfleet uniform adult-onisees and other junk merchandising.
It's not targeted for us, the fans. It's targeted for non-fan friends of fans, significant others who have absolutely no clue what Star Trek is, such as my wonderful wife, for example, who bought me an
Enterprise-shaped pizza cutter many years ago. Bless her heart, she has barely an idea about Star Trek, outside the limited conversations I have with her about it, and she thought it would be a neat thing to get. I would never buy such a thing for myself, but it's sitting on my shelf with the other collectibles, nonetheless. Such people see something Trek related and buy it for that special person thinking, "Oh! That's one of those silly little
Star Track things that he/she loves so much. I don't think he/she has this yet, but I'm sure he/she will LOVE it! I'm getting it!!"
THAT is the target market for whom these things are focused. Most fans wouldn't buy such shit. And most "officially licensed" shit is just that - shit. The fans' loved ones and friends, however, who don't know any better? Yup!
