It is impossible to "impede the progress" of someone who is standing still.

Obstruction has two intonations, 1) the obvious physical act and 2) the psychological act. In the second, the OBS still exists.

Example: R on 2B, a play is in progress in RF, he's standing on the bag, looking at the play. He mentally commits to attempt 3B but as he turns his head, F6 is standing directly in his path.

DEF needs to get out of the obvious basepath, or running line, and all is well. If they don't OBS should be considered.
