As for the chart provided, I can't see anything related to the Bitcoin value with time. Value can be defined as the relation of the demand and supply. Here we can see only supply. We can conclude that the value is zero if there is no demand.
I would agree to this, it's a good indicator but like Magiklair is saying the value wouldn't be zero if there was no demand.
I think the graph is not about bitcoin prices, but the graph is about when bitcoin will be mined. its estimated bitcoin will be exhausted mined in 2037 and above. which is the problem whether there is inflation or not in that year.
