Funny enough, this comes from my own pet passion that I think Catholics should support. Space settlement. We aren't over-populated on earth, but if we were doing our jobs as parents and care-takers of creation we would be. This we should support the only thing that reconciles our injunction to fill the earth and the fact that the earth is finite. If our Lord doesn't return first and we are faithful to his teaching for our families we need to expand into the cosmos.

Bitcoin however, cannot expand into the cosmos. I can't wait 9 years for the block chain to settle my transactions if I am a star over. It won't even work between planets. Either you tolerate long settlement times, make a new chain for every locale, force far-flung places to be on side-chains, or you make something that is trust-based and social graph aware, with time and location data baked in.

I am somewhat hopeful that Bitcoin can morph into that thing, probably by incorporating something like nostr as the trust layer. We probably have plenty of time and Bitcoin is good enough for here and now.
