Its safe unless you are riding on very steep long hills. People rode heavy bikes touring before disc brakes existed and didn't die.

Subjectively, it feels as adequately braked as any of my acoustic bikes (including a mountain bike with dual 4-piston hydraulic brakes).

Can we start calling them analog bikes instead? As a guitar player, acoustic sounds very weird.

“Acoustic” is just silly, “analog” isn’t much better. I’d call them “mechanical”.
