I really hate whenever I try to explain how some bad rules can be abused and immediatelly get someone say shit like "If this happens in your group, change it" as if that would solve the problem. And whenever it is not soemthing you witnessed personally, then it means it never happens and could never happen.
Prevention is better than cure, dude. Take your vaccine so you don't get the disease. Set up a fire escape so you don't burn to death. Lock your door so people don't walk in and steal your TV. Avoid Stabby Johnson so he doesn't stab you.
And if you notice a flaw in a game system, do what you can to fix it.
If you are aware of a potential problem and do nothing to stop it, then you are responsible for it if it happens. You can't expect to avoid tragedy entirely, but you reduced the risk of THAT tragedy by a good amount, and that's not worthless. A seatbelt won't always save you, but you're absolutely fucked without one.
For someone trying to keep all options on the table, you sure are quick to remove all options from the table.
