Language is a toolkit to communicate ideas, and a toolkit frozen in glass is a useless toolkit.

You need to swap out that hammer when it starts getting damaged, or put back a screwdriver when you find out you need it again, or add new tools when you find that the tools you have now aren't fit to purpose.

And sure, there's some loose screws at the bottom of the bag, but they don't harm anything, and very occasionally they come in useful.
