Genuine question and please don’t beat my ass.

How far can Nostr go? Like being built on? What I mean is … Is Nostr a replacement for centralized social media? Or can you build more stuff on it?

Like it feels like I am using a working Twitter replacement. But what about other apps and sites like… eBay? Or DoorDash? Hell, Zillow? Like I know there are limits to the service side of things, but is Nostr just solving social media and communication? Or is it the tipping domino for our everyday lives and other services we use?
