The inability to sell certain furnishings acquired through excavation within The Elder Scrolls Online (ESO) stems from their designation as untradeable or non-sellable items. This restriction is a design choice by the game developers. For instance, a recently unearthed decorative item from a specific Antiquities dig site might be bound to the character that discovered it.
This restriction serves several purposes, including preventing exploitation of the Antiquities system for economic gain and preserving the rarity and prestige associated with obtaining specific furnishings. Historically, MMORPGs have implemented similar restrictions to maintain balance within the in-game economy and encourage player engagement with various game systems.
