The main goal I had heard is that the incentivized structure of most crypto-assets will lead to everyone collaborating together - the alternate being the state/government mandating collaboration. The solution is the later, if blockchain and an immutable ledger is the real value and goal, and the problem with the first is the same incentive structure leads to a lot of bad behaviour and unreasonably transfers wealth (or could say distributes or could say steals from uneducated people) weighted towards the earlier adopters; it mimics a decentralized and global Ponzi and Pyramid scheme, the decentralized and global part are what has made it reach the point it has and has allowed marketers and schemers from around the world to collaborate - the truth if ignoring the whitewashing done by spouting all of the supposed benefits.
