however you can accept a 0 confirmation transaction relatively safely if you were selling a coffee. What does relatively safely mean? I'd prefer transactions to be guaranteed and accounts to have a verifiable amount of funds in them - the currencies/banks we have now do this in seconds for small transactions. the official client is open source, any changes would have to be agreed by the development team but they would only come into effect if all miners (or at least 51%) agreed to the change. There's definitely space for conflict there. If the official client and/or lots of the miners decide something, it's going to be hard to get momentum in another direction, and as a small holder you will have no say at all. Given the huge vested interest of developers and miners, that seems ripe for abuse. It seems your points show you dont really understand what bitcoin is. If that's the case, it should be easy to rebut them. That you have replied with non-rebuttal rebuttals on two points and snide remarks for the rest doesn't give me much confidence.
