Yeah, its totally true most folks are just after the money. And yes, I agree – they dont care about decentralization or Satoshi vision or white paper. Thats just how (current) users are.
But heres where your argument fails: User greed doesnt change how the network works. You are thinking Bitcoins value is about how many people bet on it. Nope. Its valuable because it keeps running without needing banks or anyone in charge. Decentralization is the key. Even if everyone only used it for private peer-to-peer payments, the price might stay flat at $1. But if decentralization fails, all our Bitcoin assets becomes worthless.
If decentralization fails, Bitcoin will surely lose value. But not to a point where it goes all the way down to $1. There are many centralized "shitcoins" on the market with a high market price. BNB, and Solana are good examples of this. Since most people don't care about decentralization, they will probably keep buying and holding BTC like they've used to. It's all about the money.
If countries start "banning" Bitcoin, you can bet people will stop using/supporting it. I mean, no one would want to face fines or go to jail if caught using something "illegal". It is what it is. At least we know, not all countries will turn against Bitcoin. Some will embrace it, while others will reject it. Just like it's the case these days. So just sit back and relax. There's nothing to worry about.
