Tragedy of the anticommons

The tragedy of the anticommons is a term used to describe a situation where too many people own a thing and no one can use it. It's like a playground in a park where too many kids want to play. Everyone is trying to use the same playground and no one can, because there just isn't enough room for everyone. This can happen with things like land, patents, and copyrights. When too many people have the right to use or control something, it becomes impossible for any one person to use it, so everyone loses out.
