The Deep Space Array would be like a super long range scanner so you could spy on your neighbours although they may be really far away - like fifteen sectors (galaxy).

It would cost a lot of materials and take up a lot of space (sort of like that Argus array in Star Trek: TNG)

I'm not sure about the Warp Point thing - I'll look into tomorrow.

Also, how about a facility like a Command Centre - it could generate happiness, intelligence, military training...
