"Medicare pays too little" is based on the "fee for service" model; it only makes sense if you believe the group of people who actually use the ambulance should pay its full cost.
The options model matters: if you model an ambulance ride as a roulette wheel, you only expect to pay if you get very unlucky. If you model it as an option, you expect to pay even if you never use it. The former doesn't imply "everyone else should have to pay for my bad luck"; the latter does. It's effective persuasion.

There are plenty of services that have high fixed costs but low marginal costs, but we don't use the "options" framing. A movie costs tens to hundreds of millions to make, but otherwise costs very little to deliver. Their price are also fixed, rather than dynamically priced. Yet when a movie bombs, nobody is like "wow I guess they shouldn't have been selling an option for 2 hours of entertainment for $20!". It's a price problem, first and foremost, caused by insurance companies and medicare strongarming them.
