Locking the stitch is just to prevent unraveling of the thread. I will lock several stitches on load-bearing seams and heavier fabrics that will be under stress (hammock channel, for example), but rolled hems on light fabrics don't need it.
Your thread is going to be stronger than your nylon or poly fabric, and every time you punch a hole in the fabric, you weaken it, so I want to sew with as few needle-punches as possible. This is why I like my stitches on the long longer side of the spectrum.
I've used Lock-Tight on buttons and things that are really are under stress.
