This is something that's struck me earlier with Kickstarter with stretch goals of varying levels of cost; the inability to voice an interest in one over another. There've been a few projects where there was a stretch goal I wanted at a high amount which wasn't met, when a smaller stretch goal I didn't very much care for was made.
The stretch goal is supposed to be a logical extension of the main goal, with the understanding that if you are genuinely working towards an actual project that more money means you can make the project even better. That works pretty well when you are creating something like a board game or an independent film or a video game.
It doesn't work here because there is no actual project. They are asking for money to produce the same thing they produce now.
Nonsense stretch goals are a good indicator that the project as a whole makes little sense. You can't have a stretch goal if you don't have a legit normal goal to begin with.
