It's the best defensive option in singles, so it'll naturally be used a lot. Especially by defensive teams.
Hazards punish switching without stopping it entirely. They make it so you have to actually think about whether switching is worth the chip damage you'll be taking. And they make it so you can't just spam switching without consequences, meaning that you can't go on complete defense forever.
Arena Trap and Shadow Tag rob you of that defensive option entirely. No thinking involved. You just have to sit there and resign yourself to your fate.
