The point is that you can’t observe anything without some kind of interaction. Even just looking at something requires bouncing light off of it.
We’re used to our observations seeming passive because light is often hitting the things anyways, but the double slit experiment forces the point because the subjects of the experiment are so small that even just using ways of observing them affects the outcome of the experiment.
