I'm not saying that lumber doesn't come in sizes optimized to save time and material, that's only sensible. But as you've said there is still cutting on site and frankly there's a fair bit of it, despite what you claim. With prefab most of the cutting is done in a factory and there are very few if any cuts on site. Complete modular components are delivered and fastened together, and on site assembly is measured in weeks not months. The idea that this will not ultimately be a better way to build homes just isn't well founded. It's a better way but different and it's going to take time and investment for the industry to change. We have an opportunity here to help our country put people in homes and invest and be a leader in that change, and that's what I'm voting for.
