My only problem with the article and the comparison is that a house, real estate, has intrinsic value.
What gives a BitShare intrinsic value that makes it valuable collateral for creating bitUSD from?
What gives bitcoin intrinsic value ?
Nothing?
The idea I cannot go away (at least not that easily) like gold.
What intrinsic value does a stock give me? At least decades ago it used to be all paper and you could burn the paper for heat or worse case scenario consume it if there was no food nearby.
After all do you know what paper money actually is? It is Federal Reserve exchange notes, not much different in principle from a lot of stocks out there (especially those that don't issue dividend).
That's a rhetorical answer of course. Most of the things in our society are technically ponzi schemes based on the scarcity principle.
