But why is that especially exhausting for remote workers? Why not local ones too?
You also foucs on assigned tasks rather than a team working together to get stuff done. Sounds like Software engineers, not product engineers. If you are pre assigning tasks and working separately then yes a daily scrum has no value.
But that isn't the point of a daily scrum, or scrum/agile at all. The focus needs to be on getting value to a customer together as fast as possible - not individuals doing a task each to build to a pre-defined whole. Iteration not increments.
