The article doesn't really mention blockchain other than 2 times quickly, it seems like everyone in this comment section seems to believe that though as if they said you MUST use blockchain at every step of building something like this.
The article demands decentralisation of infrastructure, which if you want to facilitate payments like Wechat does which is a large and key component of the platform, requires some sort of consensus mechanism.
Doesn't necessarily need to be a blockchain, but something similar in spirit, and this quickly falls apart because WeChat does a billion+ transactions per day, that's about tens of thousands per second and there's no decentralised, secure solution for this.
