It scales as much as is needed, which is basically zero. The rate of growth in the number of products I buy is effectively zero. I use one shaving cream, one soap, one shampoo, one detergent, the same number I used 10, 20, 30 years ago and the same I will likely use for the rest of my life.

Also, I don't need a wall of buttons, a few inside the bathroom cabinet, a few inside the kitchen cabinet, a few at my workbench, in the garage, in my shed, is all I need.
