I see your point. But if this is a viable idea, the competitors with similar solution will appear eventually, which would sort of remove the single point of failure. On the other hand if this fails, nobody will try to get there a nasty backdoor. Moreover compared to the current state when almost nobody uses gpg because it doesn't work with their favourite cloud provider, this approach would provide a nice alternative.
