You are already paying for other people's healthcare costs, whether it's private or public!

If you pay for home insurance (you kind of have to unless you own your home outright or are renting), you're paying for other people's fire or water damage. And one day they might pay for yours.

If there's a lot of fires or water damage, everyone's costs go up.

What is this comment? Yes, society curtails behaviors?

We wear helmets and seatbelts?

Insurance is entirely about paying a small amount so that the costs of being on the wrong side of bad luck doesn’t pauper your citizenry. A single payer system wildly reduces the amount that has to be paid, while increasing service outcomes since now you can negotiate with drug companies.

I would happily pay for that kind of system as well, because I am happy to ensure that the rest of the nation is better off.

Society is by definition “forcing” people to carry the burden of other’s choices. You’re drawing an entirely arbitrary line at direct taxation. Why is it “fair”? Because society isn’t zero sum. We each give and take in different ways.
