Yeah, I think the card is meant as a double bonus for terminal collision.
On the one hand, you get an extra village, on the other hand, you get some VPs for your unused/unplayable terminals.
I don't think it has to be nerfed, it's probably fine the way it is.
You don't often have $4 to spare anyhow.
If the buy-clause would be changed to a gain-clause we might have a problem.
