Croesus is a great thinker in this space.  I liked this:

> The reason you can’t copy and paste Bitcoin is that a Bitcoin is not a jpeg made up of 0s and 1s.  Instead, when you own a Bitcoin, what you really own is the consensus view of every computer on the Bitcoin network that you have authority over 1/21M of the Bitcoin supply.  In that sense, you don’t own anything tangible; you own an inalienable property right.

Bitcoin is a social convention agreed upon by its participants, enforced through tech.  The tech, without the social convention, is worthless.  Would love to see more made of this point.
