Yes sir. Like two sim cards registered to one person or having a business account and a personal account registered to the same individual.

That's just two different npubs right? You can create as many npubs as you'd like and use them in any way you want. I have npubs for Listr, Ostrich Work, Ontolo, etc. (basically all my projects).
But, they're just different identities. You can't have two npubs that both resolve to the exact same kind:0 metadata (profile). When you create more than one npub, they are distinct.
