You have an (ID/physical body) to Navigate and experience the real world..

Of course it makes sense to have an ID/Npub to navigate the digital world. You can’t/don’t change bodies to go shopping , travel or go to a friends house to socialize.

But what sets Nostr apart is you can create different digital bodies (IDs/npubs) to explore and experience different digital worlds….in a different way,..or through someone else’s experience…or not.

That’s Freedom.
