People gotta eat. I don't know why you would think it rides better than steel or aluminum. Like I said, the reason people are interested in them is the low equipment costs required to build. That doesn't mean they are cheap to make as a business because labor costs are relatively high. Home builders have little equipment but lots of time. I have no idea why you would buy one unless you just like the idea.

However, the law of bicycle marketing says that if you think it will ride better than steel or aluminum, it will due to cognitive bias.
