What you’re describing is more like mostr.pub where fediverse users are writing events with nsecs tied to their Mastodon accounts. I don’t know much about how that works though, but I’m pretty sure nostr:npub108pv4cg5ag52nq082kd5leu9ffrn2gdg6g4xdwatn73y36uzplmq9uyev6 isn’t sitting on a pile of nsecs.
