IO Pin acces through user space = reducing NAND Flash lifetime?

Dear community,

we are starting with our first linux project. Before we were just working on micros without OS. As we wonna run the applicaiton in python there is no simple IO register access (we use a MX6ull at the moment). If we toggle a pin (5 leds) through the user space it is always a sysfs access which will result in a NAND Flash access, am I right? As this will cause a reducing of the lifetime of the NAND flash for just blinking a LED? Can this be neglected? Do we have to write a C program which access the IO pin directly to solve this?
