Maximum thrust is not used by airliners for takeoff, "takeoff thrust" is computed using the final weight and balance figures and is usually not maximum thrust but a percentage thereof. This minimizes engine wear and allows a safety cushion of available power if needed.
It's also to make it more comfortable for passengers as well as to reduce stress on the airframe. Theoretically it could be possible for a plane to be made with engines so powerful that they could rip themselves from the wings if they were turned on full blast while the plane isn't moving.
