It's very easy to make a "whitepaper" about solving some important problem using Ethereum/Web3/IPFS with whatever interesting kinds of voting schemes and incentives. Whitepapers of all kinds are basically designed to seem impressive and downplay problems, just like any other promotional material.
Deciding whether the organization behind that whitepaper is legit, competent, and serious enough to actually make it happen is much more difficult than ticking some bullet points. Front end development is hard to do well, cryptoeconomic mechanism design is really difficult and prone to horrible failure, marketing is hard, profit is hard, etc etc.
(As an aside, I'm curious how many people actually understand how IPFS works. Are we all clear that it's not a magic place where you can upload things to make them available everywhere forever? In most important aspects it's equivalent to BitTorrent with Magnet. You still need to seed!)
That all said, in the sense of the "Keynesian beauty contest" it doesn't really matter whether a team will actually deliver anything good. If the web presence and whitepaper hype is cool enough to generate a good buzz, that's enough to generate a speculative wave where you hopefully won't be part of the crash!
