Are you making a reference to the Tyranny of the Rocket Equation? The Earth's gravity is so large that it's almost at the limit of chemical rockets. A typical rocket is 90% propellant by mass, 8% structure and 2% payload.

Yes it’s a reference to the tyranny of the rocket equation. The same principle applies to wagon logistics because the animals and driver are constantly eating the food the wagons carry.

FTA: "We may call this problem the ‘tyranny of the wagon equation’ as a number of readers have noticed the similarity to the tyranny of the rocket equation."

I’ve wondered if this belongs on the Fermi paradox pile. Many biospheres may be more massive planets that are so hard to get off that a space enterprise never starts.

Meanwhile lighter planets might have trouble holding onto atmospheres.

It's mathematically very similar.
