The big challenge with your whole proposal is that bitcoin doesn’t necessarily solve any real core problems. Most digital content is available in both “free” & “paid” format. Or at least “paid” and “premium” with a side of “illegal”.

If you really enjoy an album of music, it’s generally pretty trivial to purchase a “copy” of that song. There’s no real need for “bitcoin” here, there are lots of websites available for this stuff. Movies can be a little more annoying, but this generally has to do with accessibility in specific regions & languages. The primary hurdle is copyright protections and international ownership laws, not payments access.

And instead of micro-payments, many artists have moved to the sponsored “Patreon” model where they get paid for the work they do, typically in advance. The primary problems here have nothing to do with “bitcoin” or money transfer but instead with connecting people and messaging them about new content.

So really the only missing piece here is the monetization of the “like” button. Except that actually happens. “Like” buttons are that which helps to pay Facebook’s bills. The content providers may not be getting the full value we expect them to have, but Facebook/Twitter/Tumblr/etc are the gatekeepers for web traffic and they need to get paid. I don’t see any reason for FB to change the business model of receiving money for driving web traffic.

Is there something I’m missing here?
