Coming at it from the utilitarian point of view (for sake of argument -- I am not a utilitarian[1]), does it really need to be argued that every humane person should naturally wish to respect individual consent to the fullest extent possible? The only remaining question should be to determine to what extent this is possible. Is there a way to get the road clearing paid for without violating the consent of those who don't care if it's cleared or not?
It turns out that we can form systems whereby this is possible. For example, take a home owners association (HOA). It violates no consent to have contracts that stipulate that you must pay a yearly fee (or "tax") to join the HOA. So there you go, the snowplowing problem is solved, all without any violation of consent.
If you're creative, it turns out that you can solve all of these dilemmas, without resorting to government fiat, which of course can only be implemented by being willing to point a gun at your neighbor's head. No humane person would prefer this, ergo actually humane people would seek more creative solutions.
