Well now we're getting philosophical and that's my favourite place, so I'm wondering, if the most successful blockchain in the future measures people's  hourly workrate value, would you call that a currency?

I'm imagining this currency could be built in a way where the only capital was the hours banked. So there would be no rich people, only people who were in demand at that moment.

I think I might like that world, because a hard working plumber would be doing very well and an entrepreneur who didn't actually do any work would be doing badly. That seems like a very fair world to me.

In fact, the way Bitcoin only measures accumulated wealth - because that's all gold and silver can do - might be short sighted. cryptocurrencies can measure things that metal can't and maybe they should?

But would that be commerce? Would that be an economy?
