No, that paragraph is correct. You may be either missing some context or using a different definition of blockchain that doesn't apply to crypto and web3. All the selling points that crypto people have said about blockchains are completely false. It is just a hashed data structure but that's the point -- how is a hashed data structure going to solve inequality, minimize global energy usage, stop wars and feed the hungry? Of course it can't, but you can still see plenty of those outrageous claims floating around on crypto twitter from people who should know better. As far as hashed data structures go, it's not even a good one. It's universally bad at everything for a number of reasons. This is a database system intentionally designed so that writing to the database becomes increasingly and artificially expensive and/or wasteful, for no actual benefit. There's nothing interesting about them. There doesn't need to be a single person collecting the dollars for it to be a ponzi-esque scheme. The reason people call it a ponzi is because there is no actual profit anywhere in the system nor is there any reasonable mechanism for any typical investors to get stable profits. It's all speculation. The only way you can make a profit from "investing" in crypto is by selling to someone else at a higher price. Yes, ponzi schemes can continue indefinitely if people keep dumping money into it and nobody shuts them down.
