The biggest barrier to thinking in bitcoins is that I'm not paid in bitcoins. When someone hears that a TV costs $600, what they think isn't "160 Big Macs" but rather "about 3/4 of my paycheck." This is why rich people do seemingly crazy things like pay $500 for a T-shirt---because it sounds to them like $1 does to you.

People who start bitcoin businesses are at an advantage here. They know how hard they work, so they know what a bitcoin is worth to them.
