> the friction of money actually being involved ... makes it not worth it
This is it. There are very few people who live for this level of financialisation.
So blockchains don't necessarily financialize things that aren't already financialized, they just tend to make money flow in a more direct way from a group of people using a service to a group of people hosting/providing it. Instead of paying using a micropayment of attention that gets monetized through a complex and often bespoke advertising arrangement, you can pay using a micropayment of a recognizable asset that has actual market value.
Personally, if I could click a single Apple-pay-like button in my browser to attach say 0.5 cents of postage to this Hacker News comment to get it to post, I doubt I would think twice about it. In fact, I would probably participate more confidently knowing it's a deterrent for bots (less of a problem for Hacker News, but a huge problem on Reddit and Xitter).
I suppose there is a certain sense that transaction fees go to people providing services to the blockchain... but i would mostly describe it as paying rent and not actually paying the person responsible for the service.
