Its all just virtue signalling to special interest groups, even narrowed down like that.

You are making the assumption that Nostr = Bitcoin Only, where I suspect that it is actually Nostr = Bitcoin Majority! There are a handful of other coins that have some form of utility and store of value over time. I, for example, have a liking for Litecoin and Cardano as well as Bitcoin. (Putting all of our eggs into one basket is very dangerous! We should be very wary of the totalitarian approach to anything - Even Bitcoin!)
