These guys take a lot of space to form a proper orb web. There’s actually some occurance within the hobby and there are people in japan that keep similarly sized orb weaver species for “spider fighting” obviously, i wouldn’t recommend that last part, but the spider as a whole can be kept with the proper enclosure and care. It just takes a lot more effort than most other arachnids.
And of coarse, if we are completely honest with ourselves, we can all agree that the critter will fair better in it’s natural home than in our care. It’s just honest. That being said, there are plenty of people that keep WC critters.
