I am a stacker all the way, but peak silver will not happen and Ill tell you why....
Right now we are in a 3 horse race for collapse. It is neck and neck, between financial melt-down, climate change and resource depletion. In my opinion, the money market may just be pulling ahead for the medium term. Infinite growth on a finite planet is delusion, but sadly, our fractional reserve, debt based monetary system means that without constant growth, things fall apart as we are seeing around the world now.
What does that mean long term for silver? Industrial demand will decline. All those solar panels, electronic widgets, super computers will never be built, because we simply don't have the financial resources to drive that kind of growth. Even if we had the money, we lack the energy (oil) to sustainably generate it.
It is the same argument as peak oil. Will we run out of oil? No. But will it become prohibitively expensive for the majority? Yes. And once that majority can longer get to work, they stop earning, start defaulting on loans, lose jobs and don't need the oil anyway - so we won't run out - a proportion will stay in the ground.
