Intra system trade ship

[Norm49]

Blockading a world doesn't require complicated intra-system trading. It could be done as simple as making buildings unable to fetch from buildings on other worlds, and vice versa, if there is an enemy spacecraft in orbit (with a posture that isn't hold fire).

Ok this could be a solution. It remove some deep since we can't see the ship and track them down but it will be better then what we currently have.
