If there’s only ever one avenue of attack, sure. Your example posits that encryption is the only security layer that exists, which is laughable. Most security breaches happen at the personnel level, not the technical one.
A site does not “become facebook” just because it’s not 100% decentralized from every other possible service. Countless other factors go into it. Not the least of which is the nature of the people running it. If you run a service, and make it nigh impossible for a general public (your main market) to use because you fear it will become compromised, you are basically saying that you will compromise it otherwise, and probably shouldn’t be running that service.
