Let me be the first to say: I don't get it, why is this a thing and why is there an entire company built around this product? Which apparently requires I screw a coconut to a self made device and then put it on the front of my bike. Is this just satire of modern startups or are things actually this ridiculous?
Because the economy no longer demands that everybody work in fields or factories, and no longer demands that everybody spend their money on essentials. Basically, things like this are a glimpse into a post-scarcity society, where people make and buy things "just because".
Because people will buy things "just because".
