I can't really disagree with anything you are saying, but you can't force the designer at gunpoint :) All I can imagine is that perhaps a vendor with the ability to invest in an instock version may make a deal with the designer if they are amenable to the idea, but apart from that, if the designer says no, then that's all there is to it. It's a shame, but at the end of the day, there will be lots more interesting keycap group buys, and so long as this hobby retains control of itself by using its members' creativity and the willingness to self finance and control itself, then the next Olivia, or Mizu, or Darling may be just around the corner.
