I'm looking for a way to prevent placement of bedrock in survival. This may be achieved by an NBT TAG, a command block or else. If you know a
/give command that will do the trick then that would be great.
A command block that destroys all bedrock is also okay.
I need this because I'm making a vanilla server that uses custom villagers as shops. However, the only thing you can't obtain in Minecraft is bedrock, so I will be using it as the currency. I need to make sure it is unbreakable though, so nobody will build a house out of bedrock or do something else of the sort.
