We oppose this fork primarily because we see bitcoin as a challenge to bad money and bad governments. We don't see bitcoin as a fancier way to do the same old things. As it runs now, bitcoin is exactly what we want. As it runs now, bitcoin is sound money that governments cannot control. Yes, that means the poor will not have easy access. No, that's not a problem;
nice things are not for the poor. Nice things have a cost, and poor people can't pay by the very definition of them being poor.
They don't have to all be poor though! Being a billionaire has never been so cheap as it is today! 10 bitcoin is 1 billion satoshi (the true unit of account recorded in blocks). That's like 3k USD right now.
First you say that Bitcoin is not for the poor, but then you say that it's very easy to be not poor. So, while not technically a contradiction, this leads to the conclusion that Bitcoin is for everyone (which contrasts with Bitcoin is not for the poor). So, which is it?
Also, saying that Being a billionaire has never been so cheap is just oxymoronic, unless your definition of billionaire doesn't actually involve being rich. If it's so, then being a billionaire isn't actually impressive or something that people would want or desire.
