You forgot "ridiculously expensive." I got excited by this project several years ago, but like most of its sort: it's completely inaccessible for what it is.
One obvious way to do that is to build one, or a few, giant centralized plants that pump out a zillion of these each year, i.e. economies of scale. Like Honda Civic cars or Lego blocks (which also are machined with tight tolerances).
Yes, I know that the founders want these to be manufactured in a decentralized way, all over the world, but that's not how economies of scale work. Systems that can be run decentralized (e.g. email, Bitcoin mining) often end up becoming centralized anyway.
In other words, stick construction has been public domain for so long that it would be impossible to even acknowledge its creator and significant contributors.
