Maybe their quick-healing trick and life-extending technology only works with us (as Ra said in the movie "That's why I chose your species; your bodies... so easy to repair"... although in that movie Ra wasn't a Goa'uld as we now know them, but a critter more like us who was dying when he found us and learned he could "move" into us).
In the context of discussing the series, we have to assume that what we were shown in the movie was figurative or just plain inapplicable. As far as SG-1 is concerned, Ra was a snake in the head just like all the others. And I'm fine with that. I can more easily accept a snakelike being wrapping itself around the brainstem than I can accept a full-sized humanoid somehow physically entering a human body and taking it over. At best, the humanoid Ra we saw in the movie may have been the symbiote's previous host.

Maybe human psychology made us more likely to be in awe of such powerful beings instead of merely fearing them, making whole societies of us easier to control, even the non-possessed, even without them always being around to apply force.
Now, that's a good thought. What is the one thing about human culture that the Goa'uld have most vigorously embraced? Our mythologies. They've assumed the roles and names of gods from our pantheons, donned their trappings, pretty much gotten wholeheartedly into the role-playing. And it has proven to be a very powerful means of control.
The Unas may well have a more basic animist belief system, and may not envision their divinities in personified form. To animists, divinity is the moon, the earth, the sky, the water, the prey. It's not a bunch of people that supervise these things, it
is these things. It isn't that easy for a Goa'uld symbiote to possess a stream or a cloud and issue orders from it.
