Right, because the cost, a measure of human value, is too high. Humans could make them, but we don't value the automation. It's cheaper for a human to do it. We've had ATMs for how many decades? And yet we still have staffed bank windows, for the edge cases the ATM can't handle, such as rolled coins. Sure, some rolled-coin ATMs exist, but they're more expensive. It's usually cheaper for a human to handle the rolled coins and other bank edge cases. Same with self-check and alcohol age verification. Same with last-mile driving for self-driving cars and trucks.
