Certain animals don’t really roam as part of their lifestyle, most tarantulas are ambush predators, if you put a tarantula into a hole and regularly give it food, it doesn’t dream of the outside world where it can roam freely, roaming freely is its worst nightmare because that’s how it gets exposed to predators… tarantulas find a hole where they constantly get food and you can presume based on how they live in the wild that they’ve found the best hole ever.
They also show clear signs of stress when they are stressed, and they show less of those in captivity than in the wild.

That’s my argument for tarantulas anyway.
