Let's say you build a lot of roads. But there is nobody lives there to use them. Is it valuable? Not yet.
Then you build a lot of houses. But nobody wants to live there, because there are no jobs and no other people. Is it valuable? Not yet.
Then you build a lot of factories. Now there are jobs, and goods to trade, and people can move there. All the infrastructure from the first two steps becomes valuable. Before it was just potential value.
Of course the value could also be created by having farms, or maybe you just have really good internet connections and all the digital nomads want to live there. Different ways to create value exist.
So which one is the "valuable" part? All of them together are valuable, but missing one ingredient makes everything useless.
Ethereum is an ecosystem, and you need a number of things together to make it valuable. DeFi is amazing financial infrastructure that is one of these elements. It's not that DeFi is bad, it's actually the opposite, other parts are not there yet.
And if you dislike current RWAs (a term that is very broadly defined), yes we can absolutely build more digital native tokens.
Just don't expect me to love them if they're just a digital casino. But you can totally still build it, there's nothing for me to stop you. I just work on the infrastructure, Ethereum is free for everyone to build on.
