I prefer root canals as a comparison.

Some people don’t brush their teeth well or often, or eat a bunch of sweets, and need root canals. It may be that they could have taken action to prevent it by exercising good oral hygeine, but they aren’t out there getting root canals for fun.

And then some people have a genetic predisposition to cavities and tooth decay, and even with good oral hygiene they still might end up requiring a root canal. And some people end up having an injury that results in a root canal, completely outside of their control.

But nobody is out there getting “recreational” root canals. The idea is stupid. And absolutely nobody is trying to restrict access to root canals because some people don’t brush well, or gasp had more than one root canal. Because root canals, though not the preferred choice, are a necessary part of dental care.
