Saylor isnt ONLY about NgU, he just thinks bitcoin is the best store of value in the world.  Nobody could ever have predicted that 15 years an open source project would have that property (yes, i know the genesis block!).  But its an amazing achievment.  Bitcoin is many things to many people.  No one person can say they know the ONE use for bitcoin.  But 10s of millions of users have chosen it as a store of value.  We, the bitcoin community have to respect that, and not rug the users that have put their trust in the community.  Bitcoin is not all about NgU, lots of things that can be built on top of it, or around it.  Nostr being one case.
