There are many classes of jobs that you must be physically present for. You must be physically there to make food, to build, to repair, to be security, to treat patients, to drive a bus, to build a boat. Things walk off of shelves if you don't have employees manning checkout stations. These all legitimately require your physical presence.
A lot of those things are already automated. Machines that create pizzas, burgers, cocktails, robots that weld, security robots, remote medical care, driverless transportation.
The rental car place had people there... two to move cars and clean them, and one to sit in an exit booth to check IDs against contracts and lower the tire-ripping thing. But they didn't need three people idling behind desks waiting to process people's policies.
