using #nostr through #tor seems to be fairly ok for #privacy too
the easiest option by far is web client through tor browser, 
#grapheneos and tor-native app surely too
 maybe add #onion relays
maybe paid ones to keep spam at bay
and if paid  then in #monero 

 We still really need a non-javascript nostr client with people hosting copies of it on .onion addresses 

 #nostrudel can be hosted on #oonion.  
It is even included in #start9 

 It relies on javascript 

 Should not be a problem if self-hosted? 

 Not sure honestly, don't know enough  

 Or use #whonix wherever
