That's a complete bastardization of the concept of "trust" as applies to distributed systems.

You're not 'trusting' a single entity in that case because you're making literally all the information public for anyone to see, use, resell, etc.

That's like saying we shouldn't have to trust Equifax, let's just make everyone's name, address, SSN, and credit history public on the internet to begin with.

There are plenty of distributed file systems that securely store confidential data on untrusted nodes by having well-design encryption. Is there a reason for which it would be worse with blockchains?

The whole point of social media is making that information available to people, though.
