Skipping El Zonte (aka bitcoin beach) but covering btc use seemed like an odd choice. I was told it was mostly used by bitcoin tourists and foreign idealists. It was funny being told by a shop they don't accept credit, but only bitcoin or cash lol.
They're different. El Zonte (aka Bitcoin Beach) is a town that exists in the west of El Salvador, and Bitcoin City is a new development project being proposed in the east.
Skimmed it, interesting thoughts overall.
