It's not a matter of requirement, it's a matter that they want to. It's their project. Since they want to, I think crypto is the best technology available for that today.
I might be wrong, but no one responded to my question with an answer of a better solution than crypto. All they say is: "should not do it". Well, the question was not whether they should do it or not. They already did.
"Don't do it" can be an acceptable answer to "what's a better solution" depending if, from your viewpoint, doing nothing is better than doing the proposed. E.g. Q: "what's a better solution for schizophrenia than lobotomy" A: "Not lobotomy, that's sketchy as can be".
You think crypto is on the net positive side of nothing. A great number of HN do not see it as such they see it as a constant source of scams, funding hype source, fraud, speculation, laundering, and so on with little to actually show in the way of being the world changer it is always promised. The point of that isn't to bring up a debate about if crypto is or isn't so, that conversation has been rehashed a thousand times here and nobody really wants to touch it with a 10 foot pole plus much better resources on the topic exist than comments, it's mentioned as why that portion is wary of a product which puts a lot of spotlight on crypto payments being a core part of why it exists instead of just focusing on the initial crypto based revolution it is already promising: a p2p decentralized browsing experience. Combine the two and you've got something that for many is squarely in the "I'm not going to touch this until it is shown to not be like the other stories and wish it wasn't about payments" camp.
I'm going to tell you a short story. Have patience please.
I consider my industry to be Media. I wanted to be a Journalist(TM) when I grew up. Won a contest...went to a major paper in Boston as part of a group of "those that will one day be Woodward and Bernstein." Then Youtube happened. I pooh-poohed it because I couldn't wrap my head around why anyone, in my thoughts at the time, "would want to watch a bunch of amateurs do x."
Fast forward to today. I watch more YouTube than Netflix and Prime Video combined. These are the only two services we still pay for...we used to also have HBO and Acorn, but they are both one trick ponies and are not adding enough compelling content quickly enough. Also after HBO ruined ASOIF, they landed on my no-go list forevermore. Acorn is simply too expensive for what it offers. It might become for compelling if it were to expand to the Scandies...
I currently maintain a folder on my desktop (one of hundreds) called The Olsen Meter. And in the folder I save every article I come across about industry people-in this case finance industry folks-who I feel are making the same mistake I did all those years ago by pooh poohing crypto. The problems will get worked out...they always do. The energy issue is a sideshow. And mainly bandied about by those who (I feel) are reacting out of nervousness about the future and the unknowns. Crypto is constantly maligned because of the hacks and thefts, but the most stolen currency in the World is/was/always will be the US $100 bill. To the tune of Trillions. Crypto and is multi-billions have quite aways to go before it even comes close.
As to whether or not this will solve the micropayments problem, maybe not but I like the idea of it as a stopgap. Until someone builds something newer and better. And if it keeps journalists from selling their souls to corporations via ads, then the Devil I know and like will always be a better deal.
Last thing I'd like you to consider: How does Dr. Beverly Crusher pay for fabric on TNG in Episode 1? Now before you dismiss the question, realize that she has never been on this planet before, this is the first time they (the crew) have met the Bandi and she procures a whole bolt of beautiful fabric with one sentence? How does the vendor know whether or not she's good for it?
