the analysis is tripe.
There is no way to know "70-80% of all bitcoins are owned by a few interests."
With bitcoin all you can see is wallet addresses, and the coins in each address. There is no way to know who an address belongs to (unless they publish they own it), and one person can have multiple addresses. So while you can see every bitcoin in existence on the system there is no way to completely know who owns what.
Similarly, the statement about analyzing and finding transactions can't represent valid commerce is baloney too. I've personally paid for things like domain names and web hosting using bitcoins. That's real commerce.
