There are things that people may have a "right" to do, that can cost the government huge sums of money to take care of them, that the government ought be entitled to take such right away from them.
For instance very few smokers can pay the huge costs of their care as they slowly die of lung cancer
Few motorcyclists can pay for long term care if they get very badly hurt.
Few alcoholics can pay for long hospitalization when they get brain damage.

The rest of us ought not have to pay for their folly.
