It also is very important for scaling the network. Tor's model has led to a flatline of around 6000 relays on the internet for the last 10 years. When you can get paid to support the network, you don't have to be wealthy to provide capacity to the network.
The lack of this was my main gripe with Nostr. With this in place and various schemes for monetising relay service Nostr has a real chance of becoming a straight up internet protocol, which IMHO is essential to really have a shot at taking on the woke social media censorship and spying systems. And I'm especially excited about the idea of this bringing more people into contact with LN and starting to really make the banking and payments systems sweat.
