Not quite - those players in their own ships entering a system they should not be in could be captured, if they are foolish enough to go without proper precautions (i.e a lot of heavily armed buddies!)
It's just an idea which will probably never happen, but a quick look at human history certainly shows precedents.
For example, you hyperspace into a new system, only to find Bubba's Love Dungeon. You were silly enough to go without friends, and now Bubba has caught you, disabled your hyperdrive (or simply removed all your fuel) and now you are stranded at Bubba's whim.
Even worse, all the ice cream has run out.
Now Bubba is generous enough to give you a choice. Either fight at Bubba's pleasure, and maybe win freedom, or wait until more ice cream arrives. Or somehow hope someone else arrives to rescue you. However, if they don't come prepared too - you can probably expect to fight them over the ice cream
