USE-CASES.md has a few ideas about how it might be used.
You should be able to have your work or church or sangha ID seperate to your activist ID until one day (at your absolute discretion) you want to prove the relationship.
Take a look at an experiment I vibed which uses zero knowledge proofs to assert the relationship and deliver on nostr's promise of portable reputation.

I personally think WoT is antithetical to bootstrapping disposable npubs without something like this.

we did some zap tests on this note… your profile only specifies a nip05 nostr address, but not a lightning address, so we tried to zap your nip05 address.... we made six attempts to⚡zap this note, at wuji@wuji.foo, over a period of 1 minute. in each case, we found that your lightning address service or server did not respond correctly. if you wanted to fix this... you could try getting a free rizful lightning address -- https://rizful.com ... if u get it set up, pls reply here so we can do this ⚡zap test again.
Exactly, many use cases. All the stuff you mentioned + infinity. Would be a great tool for P2P exchanges within your digital web of trust while staying anon at the same time etc. Might also solve the "issue" some people here see that everyone only talks about Bitcoin 😄
Yep, there are billion dollar web2 SaaS b2b products that could be rewritten to run nicely on nostr and it's identity / auth. Huge potential but its all very b2c here at the moment and getting business to change habits is an unnatural act.
Looks like we'll simply have to make these businesses then obsolete ✌️
