Minecraft wiki entry for Hiding_chests, associated text: If your chests are in plain view when you're in multiplayer, everything you have may be stolen, and you may never see it again. Ender chests are useful, but in many circumstances, you will have more items than the ender chest can fit, especially in servers where the ender chest space is made smaller. Shulker boxes are very helpful, because full shulker boxes can be carried around in your inventory, but shulker boxes are very expensive and require rare items to craft. Also, if you carry an ender chest or shulker box far from your house, you would lose it if you die. Therefore, it's very beneficial to know ways to hide chests, to protect your most prized possessions.
