The issue arises when multiple people all get sick at the same time, which is much more common than random chance would have it due to how contagious cold & flu (and COVID) are. A workplace that can handle half the staff gone for a day without falling behind is gonna struggle to find stuff for people to do when everyone is there.
This is reason for having more lenient sick policies, not less. Generally only symptomatic people are contagious (COVID being an exception). Even mildly sick people should be encouraged to stay home until fully recovered to lower the risk of spreading it to the rest of the office.
