For many, the most constraining resource is time. And you can't buy that. It takes years to spin up a new factory and production line and then transfer the implicit knowledge from your initial production line that provides the quality in the first place.
lmao, not everything is quickly scalable. Take quality lace which is still a very manual process, the highest quality brands most people working on these products are well past the age of 50. There's no one learning to make it and it takes many many years to get skilled enough to do it quickly. Also including apple in premium brand? They make cheap computers.
