The entire day on a call with a headset is one aspect. The waste of 3 or more resources trying to solve one problem is another. Changing a solo activity into a group activity means you can never go deep into abstract thought or take the time to pause and reflect. Too many cooks in the kitchen is the old saying goes.

Isn't developing a product a team activity?

I think the opposite, why turn a group activity into solo activities?

Mob programming doesn't mean you can't work solo or in pairs sometimes when it is well suited for the task.
