There's no incentive to build weapons in space, period. There's no enemy to justify the weapons system. The only reason to build weapons in space is an addiction to weapons. If there was a cult that liked to cover everything in sombreros, they would probably justify putting a giant sombrero on the moon by claiming that it would yeild spin-off technologies and that it was 'inevitable'.
There is no enemy NOW. However, no matter what, once any two nations have colonies in space there WILL be an enemy.
