I love how you dismiss things that even the bitcoin wiki treats as problematic.
I really don't understand what I said that was so wrong, but anyway.
Weird how the threat of decentralization appears only when we talk about nodes, when we talk about mining it's crickets!
To me, simply running a node does not contribute to the decentralization of the network. It merely enables Bitcoin to function as intended: peer-to-peer cash without intermediaries. If you need to trust someone else, it indicates we are heading in the wrong direction.
Do the math on how much is needed and tell me how impossible it would be for someone targeting a 2 trillion market to do it!
Do what? Attack the network? The entire concept is based on the fact that such an action would be completely irrational.
