I'm not talking about trust, I'm talking about financial motivation.
We don't need to trust miners for bitcoin to work and if we do trust them, what is the downside to someone who is just validating transactions?
They built a better gold. People trust gold. They put the majority of it into vaults and trust the people who run those vaults. This is the best solution anyone has ever come up with to digitize gold. It doesn't tick all the boxes 100% and isn't perfect, but it sure does one single thing well.
The world revolves on financial transactions. I wish I could have said that I built something that can be validated by anyone at any time and then get people all over the world to freely invest insane amounts of capex/opex. All without a marketing budget or CEO. It has never been done before.
