Okay then let's compare Bitcoin to Monero. One of those is actively used as a trustless financial system because drug dealers absolutely need it to be trustless and private. The other one is a speculative bubble that is growing faster because there is no anchor to gauge the value by so people can do whatever they want with it even if it is stupid or unsustainable.

Before you say that drug dealers ceasing to use Bitcoin is a good thing..., it really says more about the ability to regulate Bitcoin and the ability to trace people than it says anything about the users of Bitcoin suddenly deciding they are law abiding. Secondly, drug dealers are forced, absolutely forced, to use your cryptocurrency, they are the few users that absolutely cannot do without cryptocurrency, at least not over the internet. Cash is still king, but only on the street. If the most "diehard" users of the cryptocurrency move on that is a signal that it will absolutely fail for all the "softcore" users who don't really need your cryptocurrency.

Most people. Almost no one has it so how can we all need it?

That’s missing the point. You could have said the same thing about the internet. But we are not collectively making this decision based on politics, the market has decided that crypto is valuable.

With the internet its easy to extrapolate value from most tasks. Cheaper, faster, easier, always available, available at a distance etc.

Why do I need a fully trustless system that is worse in every other category? Slow, more expensive, less consumer protection, etc.

At the very least its not obvious and the market has not spoken. Even people speculating use off chain exchanges, not the chain itself.

Have you ever had your entire bank account confiscated by the government? That's what happened in my country in the 90s:

Inflation was out of control and the president decided to freeze everything in some kind of desperate attempt to control it. They took away everyone's money.

People who say they don't need cryptocurrencies are way too comfortable with their banks and governments holding all the power. I don't really care how much energy it uses, I still want it to continue existing just in case my government starts getting funny ideas again.
