El Zonte in El Salvador didn't come cheap. Galoy has distributed $100/month as pension to the elders (I wonder if those are the same elders that hold people's keys?). Galoy has also insured villagers against Bitcoin going down. So my answer is just that: bribe (in a good way) and insure the villagers. One village per country.

I want LN spanning across the main chain, sidechains like Liquid and any chain with a Bitcoin-pegged token. I want an easy and private wallet (basically Phoenix but with routing on the client for privacy like in Breez) that would accept funds on sidechain by default to eliminate the steep 3000 sat fee for opening a channel. What I want is Fedimint's ease of use but with publicly auditable sidechains instead of trust-me-bro mints, and privacy would be supplied by LN.
