Would this be a good way to keep people away from you after the SHTF?

probably just better to keep out of sight, you could do what they did in the war and that is to remove all the signposts!!

Or turn the signs around to confuse people.

well, in WW2 they were expecting an imminent invasion and so to confuse the foreign troops they removed all the sign posts, i think it was just easier to remove them and throw them in the back of a truck than to bother turning them around, but hey, that would work too.
