There are a few reasons but I kind of think it boils down to biodiversity. Seasonal changes, tides, light exposure, and varying temperatures would affect the balance of diverse life.

For example, Earth didn’t always have oxygen. 2.4 billion years ago there was a bunch of microbial photosynthesis happening. Seasons and the tides affect ocean currents which moved nutrients around, allowing the bacteria to thrive and grow.

Ozone’s formula is O~3~, so the Ozone layer wouldn’t have formed either.

There are also other issues like how the seasons affect biological migration or how the moon slows the Earth’s rotation to about 24 hours/day.
