No, this is kind of a naive position.
The OP's comment is to a great extent valid.
Ambulances and their staff are extremely expensive.
Do you think in Brazil, France or Japan money just grows on trees and you can just magically buy more stuff?
Medical systems the world over are failing under understaffing and over demand - and a considerable amount of the demand is small stuff.
There are many people in socialized systems who go to the clinic/hospital with great frequency - any old thing: see the doctor. It's hugely, hugely expensive. In some cases it's merited, and I understand it's a moral dilemma because often you don't know if something is serious ...
But Emergency care in particular is bonkers expensive, even by cost not profit ... and there's no getting around it.
If people need to call an Ambulance, then get one.
But if you don't need one, get in a car and go or have someone drive you.
It doesn't matter what 'system' it's in because everything associated with 'Emerg' is very costly to the system, and it will always be a very scarce resource.
I wouldn't let anyone at my company decide for me though - if I needed one I would call.
Tesla might need a union.
