Miners. Nodes are for checking the math, but if the math is rigged by regulation, non-censoring miners are the only way to keep the power balance decentralized.

For example, if only Mara mines, only Mara builds Block templates. They will not mine transactions from a financially sanctioned country. This gives them executive powers. Basically, in this fictional scenario, Mara becomes the #bitcoin dictator.

#Bitcoin is anarchy, rules without rulers. I would like to keep it that way

That's why I think every bitcoiner should run some type of lotto miner, based on your own beliefs.

It's fine if I hate Ordinals, but you love them. I will attempt to persuade you. I hope you change your mind and see Ordinals as the shitcoins they are, but I will defend your right to mine the blocks you want to mine.

Nodes are useful for cybersecurity and too run the numbers. It's important for your stack and for consensus, but mining is more important for the network. They are both important in a game theoretical sense, bit I value mining more because of my first principles. You'll need to examine your own first principles to determine which one is more important for you.
