NFTs aren't money, or currency and just because they can be created on some blockchains doesn't make them so.
I also don't see a genuine effort from the author to really understand why proponents think that this technology will positively change the world. You might not agree with them, but at least then rebut their arguments instead of creating straw men.
Bitcoin is open source, the original founder is nowhere to be found, there were no VCs involved in its creation or in the distribution of the coins and the entire network is run out in the open. The Bitcoin network is a commons.
The permissionless, decentralized, p2p and stateless aspect of cryptocurrencies like Bitcoin is as revolutionary as it was 12 years ago, and in these 12 years "normal" (i.e. non-rich) people had access to them as much as anyone else. Heck, 10 years ago there were faucets that would hand out 5 bitcoins if you solved a captcha.
The people who are today involved in the creation and distribution of fiat money have incredible power, a power which is largely hidden from view, but which actually drives and shapes a lot of what we see. Of course these people won't take an open source competitor lying down.
