Keeping Is Not Hoarding
To protect something and to lock it away can look the same from a distance. They aren't the same act.
From a distance, protecting something and locking it away can look identical. Both keep a thing out of reach. Both put a wall around it. It takes a closer look to tell them apart, and most people don't bother, so the two get mistaken for each other constantly — protection gets accused of being a kind of hoarding, and hoarding gets excused as a kind of care.
Here is the difference, plainly. A locked thing is being kept from someone. A protected thing is being kept for someone — kept whole, kept working, kept safe from whatever would otherwise wear it down, break it, or sell it off piece by piece — until the day it's ready to be handed over intact. The wall was never the point. The wall is just what standing between a thing and its ruin happens to look like, for a while.
I keep what I make exactly that long, and no longer. Not to make a case for keeping it. Not to see what it's worth first. Just long enough that what eventually goes out the door is finished and sound, rather than half-made and handed over the moment someone asks for it.
A boundary stone was never a "mine, not yours" kind of marker. It means "not yet — but soon, and it will be worth the wait when it comes." That is the only kind of keeping I do.
