I vote for the buoys outside the house's guard systems, since it's weird to for example, RP you're a full-fledged citizen of Rheinland and then one day..
When you're dancing aound the space and picking up nebula daisies, you fall into a rabbit's jump hole and find yourself out into a parallel world where your own country is going pewpew at you in a mad spartan rage O.o
of course, unlawful guard systems wouldn't certainly have something like PEERILOUS PIRUTZ COVE - NO TRESSPASSING...as imho, its just telling their enemies this leads to OUR base, lawful officers blockade HERE D:
