The editor concludes that the government should not fund any part of its health services with lottery revenue.
Why? Because health services are essential and lottery revenue could decline in the future, leaving the government scrambling to make up a shortfall.

If essential government services must be funded from reliable sources of revenue, then it makes sense that health services should not be funded by lottery revenue because they are an essential service and lottery revenue is unreliable.
