If everything is high prio nothing is and if the backlog is always full it's not a problem if it fills up even more. If I am at the assembly line, I am doing my darnedest not to make it run faster. One can only sprint so long.
It is not a problem if you are an assembly line robot making motions. People, however, are not robots. They get held accountable by their higher-ups for delivering on these (often nonsensical) priorities, they risk getting fired when expectations are not met, and high uncertainty of faulty planning systems like that is extremely stressful in itself.
