On the one hand, in this case I don't agree with the person you replied to who thinks there would be great market demand for this (at least at the price points currently possible). On the other hand... there are plenty of things in the world which could have lots of demand for if they were sold, or if they were invented and then sold, quite often I think of something, or see someone else's idea, where I think that's the case. But even if I were the most entrepreneurial entrepreneur imaginable, I couldn't start a business around every single thing I form an opinion on it having the potential to succeed. Acting as if someone must be willing (and knowledgable enough both about how to make the thing in question and how to market it to get kickstarter traction etc etc) otherwise their opinion that it has a potential market fit is somehow invalid, just feels... mean spirited.
