I don't think the question is "Should ambulances be a thing?" though. It's a question of "Should someone in a situation where they need an ambulance have to balance the potentially life-threatening impact of saying no versus the potentially financially ruinous impact of saying yes?"
The (fairly obvious) answer to that no one should be in that situation. It's horrible. Society should find a better way to pay for ambulances. Most of the world has accepted that some system to spread the cost among everyone is better than putting people in that situation.
