It depends on your comparison; a Lack table is maybe an extreme example.
I say this because I’m currently working on a project to build a full kitchen’s worth of cabinet carcasses using good quality 19mm plywood, and I’m aiming for it to be cost neutral with Ikea’s kitchen cabinets, having sourced the plywood from a local DIY store. (Obviously ignoring the cost of my existing tools.)
Which is to say, if you could source plywood in volume (therefore cheaper per square meter) and amortise the cost of the CNC machine and other tools over time, I think it would be feasible to be close to cost competitive with IKEA‘s kitchens.
I'm not using CNC; I just agree with the previous poster that there's an opportunity. (I'd note that none of your subsequent post related to the comment you made about CNC?)
For my project, I believe 19mm is plenty for carcasses - just about every mass-produced kitchen uses 18/19mm chipboard frames, and they can last for decades, outside of abnormal abuse. The main reason for using the same size is easy compatibility with standard doors/fronts together with standard fitment hinges/runners, all of which I'll be purchasing. The tops will be either granite or concrete.
I don't disagree with there being an opportunity or using CNC, I only point out that pinning everything to materials suitable to widely available CNC is too limiting.
Like, using plywood for verticals is overkill, they don't experience any bending, while 19+19 is 48 so you might as well use glued wood board for example.
