There's a "blockchain solves everything" mentality that's prevalent in certain web3 communities.
It's fueled by the fact that there really aren't many, or perhaps any, usable web3 platforms that do anything beyond distributed ledger or NFT type stuff. Obviously nothing in web3 even resembles the scale and speed and ease of use of Twitter.
This has left the door wide open for futurists to paint the most idealistic picture possible of what web3 will look like. Blockchain technology is largely irrelevant to the projections (because it's boring). Instead, the projections suggest to solve all of the various social and legal problems in unspecified ways, with "web3" used as the excuse. It goes hand-in-hand with the idea that big corporations are evil and bad for users, but democratizing ownership will change all of that. Nevermind the fact that the big corporations are already publicly traded and you can buy a share of them today if you want, which isn't actually very different than buying governance tokens of a web3 system. The people with the most money and insider connections (to get early coins at a steep discount) are still going to be the ones calling the shots and shaping the systems to derive profits for themselves. There's nothing magical about web3 that stops people with money from buying outsized influence.
