> The fact that nobody can simply say, "here is what Bitcoin does, this is why the energy consumption is justified" is a strong indictment against the supposed value that Bitcoin brings.

I argue the opposite in a separate comment. The fact that Bitcoin has retained and increased its market value, despite having being inflationary this entire time, demonstrates the value that it brings. I can't tell you where that value is, but if it weren't there, the market would collapse. And it hasn't.

Perhaps 10 years isn't enough for a speculation bubble to burst. But then, at what point would we say that there isn't a bubble? 50 years? 100 years? One might ask the same question about gold since we left the gold standard. Is indefinitely sustainable speculation a bubble at all? Or is that what we call a commodity?
