The daily routine of a stargate team is, that they dial a new coordinate, step through the gate and arrive at a new unknown world, stepping out of a stargate, most times located in the wilderness and completely unguarded.
While this is acceptable in cases of uninhabited planets or where the inhabitants are not aware of the stargate it seems completely stupid in case of planets that are controlled by the goa'uld or other stargate aware fractions. Humans on earth of course hide there stargate in an underground base, heavily guarded and sealed with an iris.
The explanation that the goa'uld think they control the network and so do not think about the possibility that an enemy could use it to sneak in their location sounds lame. They are rivals and had other enemies even before humans become stargate travelers. And there are no great cost to guard a stargate.
Why does the ruler of a planet not move the stargate to a safe (to control) place like humans did? Why not build a kind of "airport" around it?
OOU it is of course otherwise all the sneak in and guerrilla plots won't work. Especially in the early episodes. But was this complete ignorance of the stargate regarding security ever addressed in universe?
EDIT:
Why do no other planets in the Stargate universe have a iris? Thanks for the hint, but it does not answer my question. It does not say why people who are aware of a stargate and use it, do not guard it, as they would every city gate, border, checkpoint etc. Especially if they are as military as the goa'uld and have enemies that could use the stargate to enter their realm.
Even primitive cultures guard every door in the city walls. And even if the stargate is the door to the gods, it should be sourounded by a temple and worshipped by priests awaiting the arrival of the gods. And as a goa'uld I would at least monitor it (camera?) to be informed about activations.
It boils down to 2 scenarios:
- Stargate is used often and by many people => It would be moved to a logistic reasonable location, surrounded by a facility and like any airport, harbour etc. guarded.
- Stargate is used only by the worshipped "gods" => People would build temple around it, guard it with priests and the "god" will of course be very interested if anybody else comes through so he will at least monitor it.
Perhaps I can shape the question a little bit more. I'm not asking you to invent justifications:
Is it just plot convenience and is never lampshaded in universe? Like Daniels asking why the stargate is not guarded and Carter giving an absurd explanation or O'Neill giving a sarcastic comment?
