Because accidents happen?
Why do we need any form of safety precaution?
I don’t intend to crash my car. I still wear a seat belt.
I don’t intent to burn my house down. I still have a fire extinguisher.
I don’t intent to chainsaw my leg off. I still wear safety trousers.
I don’t intent my furniture to fall on me. I still secure it to the wall.
Or keep all communities public and stop using walled garden communities full stop. Along with keeping forum threads alive for easier documentation and searchability.
