You're missing the point. You can't realise good defences inRP. NPCs can't fly and their number is rather low, stations are weak, w/e.
I recall Malta having planetary defense grid with nukes, but that doesn't stop 8 legates and 2 full solaris osiris to hang right outside the docking ring. Nomad patrols in Omicron Iota can't hit anything fighter-ish while they should be instantly pwnt, as well as capships, and stuff.
So is Gallia, sneaking in pwning NPCs left, right and center doesn't mean you can do the same within RP. In theory that Guard station would block the exit from the minefield and send a bunch of patrols to vaporize the intruder.
