In short, the blockchain solves an arguably near completely-irrelevant problem for most people where, say, a bank can freeze your assets because the only one who can prove you own those assets is that bank, or something like Google can delete your data if they don't like it. There ARE theoretically valid uses for a blockchain if you stretch believability, like storing the MD5 of an executable so people know FOR SURE that's the legit copy of the executable - but again, it's all shit that no one really cares that much about in the end.
