You obviously can drive eco without using it, but Eco mode will generally result in more gentle acceleration, which may be good in the long term for the final reduction gear in the Leaf drive unit.
From reading other post this can be a weakness.
Lots of high torque acceleration and lack of routine gear oil changes in the Nissan service schedule has resulted in broken noisy drive units at higher mileages. (from what I've see mostly Taxis)
Naturally like any car, if you thrash it, moving parts will wear about more quickly, so with Eco Mode you are limiting your ability to thrash it.
