There's a finite amount that you can save on your purchases. If you eliminated all the wastes in your spending and didn't give anyone a penny in profit, you'd accrue wealth faster but not that much faster. You still have to spend to sustain yourself and your family.
While there exists a limit to how much you can save, there is no limit on the value you can get from the things you purchase. For example, getting a really great cardboard box requires, at the minimum, the tme to pick it up somewhere for free and bring it home - $0 plus the time you spend acquiring it. However, you can use that box for storage, for decoration, as fun entertainment for an infant or pet, as material for another project, etc.
Although the box example is simple, it highlights that the more you utilize something, the more value you gain from it.
Are there things around your home or apartment that you under-utilize? They may be gems of limitless value.
