I will repeat the Dalish population is far larger than the Chasind one,If all the clans settled in one area they could form a small nation.Small but still a nation,and considering their past interaction with the humans,they wont be easily tolerated or ignored by the Chantry.The will be viewed as a threat sooner or later like it happened with the qunari.
Interesting claim, can you back it up? We know all the clans can come together for their ten year meet and greet without displacing a nation's worth of people, so I'm interested to know where the rest of this small nation's worth of population mass is hiding out.
I'm not saying every clan is the 20 odd people we tend to see in-game, because that's just as absurd as suggesting only 50 people lived in Denerim or there were only Elthina and a couple of Templars in the Chantry. But I would estimate no more than 200-300 on average due to their nomadic lifestyle and the difficulty of providing food for a population much larger than that by living off what they can hunt and forage. So unless you're suggesting there are multiple thousands of clans spread across Thedas, a claim I will have difficulty accepting without proof, and would find vaguely ridiculous even with said proof, then you've got maybe a small City-state worth of Dalish wandering around, and I think that's being generous.
Recall, now that a significant portion of the population of the Dales, if not most of them outright, decided that the Alienages were preferable to exile, and the Dalish have not been living a lifestyle since that would have allowed them to recoup those numbers.
I think they could lose themselves just fine in a remote part of the world.
