I mean that a rule is not a solution to anything. It can be a temporary measure to mitigate a bigger problem that you yourself had caused. But every rule has a side effect. So if you do not remove the underlying problem, every rule that you impose creates more problems, that become underlying problems for other rules. And so the snowball keeps rolling until it is an avalanche.
The same thing with medicine. If you do things right, you will never have high temperature, and will never have to use ibuprofenum, and it will never hurt your liver. But if you already are running high temperature, you might still want to use the drug, but then seek for ways to avoid getting into that situation ever again. I know our "education" tells us that health problems are unavoidable. That is a lie.
