Survival Commands Rules

So, I started a new youtube series. It is a Survival Minecraft world. But if you know me at all I love my command blocks. I saw some other youtubers were doing this so I decided to give it a try. Anyway, in this lets play I'll be able to use command blocks, but I've set up this rule list to limit myself and make it still survival.

1. No Spawning Items unless the given item is deleted from the world. (This means I could detect an item in a chest, delete it, and spawn it in somewhere else. Must follow rule 3)
2. If the setblock or fill command it used, the blocks placed must be in a chest next to the command block or have already been placed into the world. The blocks placed may not be harvested by the player.
3. Any teleports should be short ranged or for long range have a cost.
4. Kill Commands may be used, but the radius must be kept small.
5. Fill Commands may not use the destroy tag, but setblock commands can.
6. Scoreboards have a creation cost. Which is a named piece of wood.
7. Tags require a named name tag in a chest next to the command block.
8. No Changing the Command Block type. To get other types of command blocks, craft them.
9. Due to some people playing on the server not being super adept at combat, mob griefing is off. For Wither fights mob griefing must be turned on to make it fair.
10. Have Fun
