So I think that's where the core Patreon advantage lies; get around 1000 people to give you 1-5$ a month and you're living a middle class lifestyle with some reasonable assurance that next month you're not going to make 1/50th what you made last month. (It isn't perfect, but nothing is. There is not a single person reading this who can guarantee me with mathematical 100% precision that next month they're going to have positive income.)
In fact I'd point out that when it comes down to it, the incentives created by pervasive, automatic micropayments looks almost identical to what we have now. Clickbait, low-effort high-volume articles would rule. There would be fewer trackers, but that would be about it. I like what the Patreon ecosystem puts out waaaay better than that. I think you actually need that bit of detachment between the product and the payment, if you ever want to see a work produced with a thought other than "How many clicks can this exact article get?" Patreon artists are not severed from the need to make sure they stay popular with their base but at least they can go down tangents and be speculative sometimes without it instantly trashing a noticeable portion of their income.
That makes it pretty similar to ad-supported sites now. The difference is, the revenue comes from the user, who is more likely to incentivize good content.

That's a really good point, and as you mention that's pretty much what we have now. I would think that in a micro-payment based world, where you have to pay a bit to read an article, publishers would gain reputation to protect against this.
If it cost a teeny bit of my own money to look at a buzzfeed quiz, I'd probably stop doing that pretty quickly.
But I do agree that it isn't the best model for all sites, and it would be nice to offer micro-payments along with Patreon-style subscription, for those who know they'll want content from this site a lot. Kind of like how newspapers used to work.
About cryptocurrence, maybe look at steem and steemit.
