This is like trying the first Android beta there ever was and then saying that there aren't a lot of apps for it yet. Nearly all current users could have told him that living on Bitcoin for a week is hard to do right now because there is simply no support. This is why we are early adopters , we use something before it's mainstream. You can't actually walk up to anyone and expect to be able to pay them in any currency…
Walking up to people and paying people for goods and services is a good measure of how useful something is as a currency. Right now, it's hard to avoid the conclusion that bitcoin is fairly useless to most people as a currency, a hard truth for some. What is it not useless for? Well mainly as an investment/get rich quick scheme as well as money laundering, drug deals and soothing the paranoia of hard money cranks.
This reply is total bullshit, I know. I'm trying to connect with him on his level.
