What is a small purchase? a cup of coffee? Where did satoshi specifically say that bitcoin wasn't made to buy coffee but to buy I don't know... Xboxes? where is the cutoff from "this belongs in the blockchain but this doesn't because its too small"??
What does satoshi have to do with this? Do you believe that he was some majestic coder? Because he was not.
Bitcoin was never designed for small transactions auch as buying coffe or micro transactions. It is going to be a difficult task to get it to scale like that.
According to the Bitcoin white paper, it was designed for "small casual transactions" that are too costly with conventional trust-based online payment methods (e.g., Visa, Paypal, etc.)

I really don't see how you're still trying to fight for including all of the world's transaction on the blockchain when there is consensus among pretty much all the qualified engineers (that would include Gavin although I'm increasingly doubtful about his qualifications) that a POW system is simply not able to efficiently service this type of load/transactions.
You and cypherdoc's crew are really alone in your own little world and it's quite worrying to see you entertain this cargo cult
