I don't think you've fully understood the problem. There are limits to how big numbers (integers & floating point numbers) can be. They simply CAN'T keep increasing the numbers from expansion to expansion.

Also, by reducing the numbers the game performs better for everyone, since smaller numbers can crunch faster than larger numbers.
