Every node matters! Coretards are just dishonest.
The truth is that there are 3 forces in Bitcoin - nodes, market (here come the economic nodes of exchanges etc but also the BTC whales) and miners
"But miners are only one part of the picture. Bitcoin’s governance has three distinct roles, each essential, each with clear boundaries. Think of it as a trinity: Three elements that depend on each other, with Bitcoin at the center.
Node Operators: define and enforce consensus rules. They validate every block, every transaction, the entire history. When BIP-110 activates, nodes running compatible software will reject blocks containing spam, regardless of who mined them. Nodes set the rules.
The Market: buyers, sellers, holders, businesses, payment processors. They collectively determine which chain has value. Exchanges provide the infrastructure where price discovery happens, but they reflect market preference, they don’t create it. If participants transact on the BIP-110 chain, that’s where value lives. The market will tend to favor higher-quality money.
Miners: secure the network with hashpower. They execute Bitcoin’s monetary policy through the issuance schedule. They order transactions and build blocks. They generate $billions/year in revenue and deploy a massive infrastructure, but their core governance decision comes down to one thing: Which chain to extend."
