Who ever said to make a block with no transactions? We are talking about COINS with no transactions.
Let me give you an example, maybe that will help you understand better.

Take a look at the link above and you will see "No Inputs (Newly Generated Coins)". This is what I mean about COINS without a transaction history.
Make sense?
Not at all that block is greater than the 50 it was supposed to be so has old coin included in it to be a virgin block it has to have no transactions. As I have said before this is just another scheme to separate people from their BTC nothing else.
