> Governments can't help but abuse their powers and eventually kill their currency.
This is an argument against USD as some kind of eternal international currency, not against RMB / EUR or another fiat currency replacing it (instead of BTC).
It's debatable whether your 1) is happening at all, depending on definitions; most BTC transactions seem to boil down to speculation. Some users do "store value", as in, they buy and hold thinking it can still go way higher (or at least won't go lower) than it currently is with a reasoning similar to yours. But given the correlation with tech stocks as we wrote before, it remains to be seen if these users can go through a financial crisis with this mentality.
Regarding 2), what do you mean by weak? The absolute value of a currency doesn't matter as long as it doesn't change too rapidly. If you need to pay $100 in a month and have some confidence about what this will represent by then, you don't need to know more, buyers and sellers can agree on a price. As long as merchants need to pay their taxes and other things in a fiat currency, you still have a bootstrapping problem with BTC.
> Some goods are stores of value but will never reach the second stage, because they're not good monetary assets.
Why is BTC a "good monetary asset"? I can buy ETFs representing commodities in liquid markets, why is that strictly worse? E.g. for whom is the "neutral" aspect of BTC a selling point?
> There are only a few things that can stop it, and none of them seem particularly likely to me.
I don't think BTC will ever go away, but I also don't see it becoming much more widespread outside of speculative circles.

One problem in this space is how discussions remain both static and hopeful. I had the exact same discussions in 2017, it's been 5 years. The 10000 BTC pizza was bought in 2010, and yet 12 years after there's almost nothing I buy that I could have spent BTC on.
If you ask me to do something, and I tell you I'm working on it whenever you ask me for a status update, how long do you keep believing? We can't prove that BTC will never be $SOMETHING. But until I actually find someone using BTC for something other than speculation or bypassing regulations, I'll have to remain skeptical.
