Awesome article, exactly what is missing from the central planning oriented dev talk. Can we get a visual version of this argument? I suspect the two-part article's length and weightiness is limiting its virality as of now.
When you consider it for a bit, it starts to seem strikingly obvious: node operators offer a valuable service to miners and users, and although right now they do so for free, when and if it starts to be difficult for them to do so, a market will form on its own as node operators and other interested parties negotiate their own rules and fees.
Blocksize should have no hard limit. As with everything else, it should be economically limited. The trick is not to panic about "how the market could possibly handle it without central planning." No one is smart enough to figure out all the little rules and stipulations for each economic relationship, let alone do so in advance, let alone get consensus on such rules. Just remove the cap and let the market work. Babying the market with paternalism in the form of artificial scarcity just leaves the space open for competitors to stick their oars in.
