no, it's not fair, but that's the inherent risk of freedom. people might not do what's best for you, or even themselves. under this model, the government actually has to cultivate a position of trust/legitimacy rather than just compelling people to do (or not do) things.
it's easy to forget that most people act with consideration and respect towards each other most of the time, whether or not there is a credible threat of punishment. we tend to notice bad behavior more in our day-to-day lives precisely because it is not the default. you never notice all the dog walkers that dutifully clean up after their pets, but you'll surely remember that one piece of dog shit you stepped in on the way to work. the news almost exclusively covers outliers.
in my state, we have mandatory shelter-in-place under threat of fines/imprisonment, but the police don't really have any way of knowing whether you are violating the order. people mostly follow it anyway, because they are convinced of the severity of the issue.
