I read the question as “How much is the whole of the Earth worm?”
Needless to say, I was wondering what the fuck was happening.
To answer the question, all objects on the Earth are given value by humans, and a human is naturally subjective. It also depends on what country you live in, as a certain object’s worth is based on how common/rare it is.
Besides, the fact that money can be printed (let’s not get into inflation, please) just further diminishes the value of certain objects (yet raises the cost, ironically). You see, the value of a single dollar doesn’t really mean much and is always dynamic.
And this question hurts my head. I’m done :[
