You make it look as if one should stay exactly on the Lagrangean point to appreciate its benefits. The reality is that spacecrafts fly on very large orbits around these points: the Planck spacecraft followed a 400,000 km-wide orbit [1] around the Sun-Earth L₂ point, and this is the same for many other spacecrafts that have flown around that place. 400,000 km is ~30 times larger than the Earth's diameter. Unless somebody has nasty intentions like e.g. purposefully crashing their own spacecraft against some other, there is no reason to be worried. There is more space around these points than here on Earth. [1] https://sci.esa.int/web/planck/-/34728-orbit-navigation https://sci.esa.int/web/planck/-/34728-orbit-navigation
