Any price that is massively-available becomes relevant and stays relevant forever.

A price has to be massively available at a point in time to matter. It doesn't have to be available forever to matter. It feels like you're conflating the two.

The price is on a downward trend, but there are hitches and setbacks. One fair way to measure it is to use some kind of average. Another also-fair way to measure it is to go by the lowest "real" price, where "real" means you can buy something like a million sticks on the open market.

When we're talking about whether we should be impressed by a price, using the lowest historical price for comparison makes sense.

(And just to be absolutely clear, you would need to adjust the metric for a product that goes up in price over time. But for something on a downward trend, this metric works fine.)
