This is a bit of a straw man - these are either all financial products or local currencies. The point is that they all convert into dollars and I will certainly never use BerkShares for as long as I live. I only take US dollars. Also, the banking structure around these things is really inconvenient. I worked a short stint as a teller at Bank of America and never once have I seen anything but greenbacks. This was in Santa Cruz county as well, where people would definitely be willing to try such crazy ideas.
