I think, that in space stage will be some soft of galactic union. That will have code of laws. If you want be a pirate, than you can do all that you want. But you will have many enemies ( like police), your friends - other pirates. If you want be decent in eyes of space police - you must comply with these laws (have no any invasions and other, I think you will can do these laws).
I wanted to do without intrusions, but I like it even more!
