This is indeed hard to solve. But there is need for a solution. Not because I want a good couch for 4 figures, but because we should have more sustainable and goomd couches. Not just for reducing environmental impact, but also for improving quality of life and financials for all but the poorest, by letting them actually get long lasting furniture.
Currently anyone who would produce that needs to compete with IKEA, and somehow needs to convince customers that their furniture will last longer. Currently the best way to do that is hand-cut dovetails and only hardwoods. But there's quality to be had with modern solutions that are muuuch cheaper than the old methods.
