You could only steal from certain merchants, though. In BG3 you can steal absolutely everything. If you go invisible first, the NPC doesn't even react when you fail. The game's economy is a complete joke, but they have time to fix that in EA. If they're keeping it so that you can steal from everyone, you should probably be limited to one item per NPC. There won't be a sensible economy as long as you can steal the entire inventory of every merchant.
