Honestly I agree with. I mean I would love to give my common cloth to my sister and have her trade me her advance cloth.

Hey

Unfortunately, it's a system that won't be implemented into the game.
As it can be abused. Players would create alternative farming accounts to abuse trading.

This suggestion has been thought before, however, it's something that's been shot down due to that.

However, thank you for suggesting it!
