The fact that aircraft get lighter as they burn fuel increases their effective range since a lighter aircraft requires less fuel to fly.

If you always landed with the same weight you took off with, you'd end up needing to make the landing gear and surrounding structure significantly stronger to prevent excessive wear over time.
