Player inventory doesn't make any sense. ... Really ? I think it does.
Right, so the inventory doesn't make sense, but it would be stupid to use realistic limits and carrying more loot than is realistic is fine.
What I say is that Arhu, when you first meet him, doesn't look like a shop keeper to me.
So when you were complaining above about Arhu taking his whole shop with him and using a '"squeeze the whole shop into my pocket" spell', that had nothing to do with the inventory, but with not looking like a shopkeeper... whatever that is?
Ya, that makes sense.
I think you are complaining for the sake of complaining.
