You obviously don't trail ride. When you ride trails you sometimes fall down. Sometimes you catch a branch with your bars. Sometimes your bike lands on rocks or logs. The down tube of an ebike frame is often where the batteries are located. This area takes a lot of abuse from the front wheel and is in perfect position to take damage during frontal impact. Look up my YT @Platinum_Racing to see an example of terrain that could very easily destroy an ebike or gas bike.
