It's not about it being just another asset any more, it's about it being a whole separate system that's immune to the pox that's ever weakening the existing one. If enough people take that point of view then it becomes a more feasible prediction.
The current shitshow is a major push towards that realisation.
If you stop focusing on BTC as a mechanism for price appreciation, you might see it just trades one pox for another. History shows clearly the gold standard doesn't prevent brutal economic depressions. It's widely accepted among economists that ending the gold standard is why the US got out of the Great Depression when it did.
A few halvings from now, Bitcoin supply will be much more fixed than even gold. Can you imagine national currencies having a fixed peg to BTC? The deflationary possibilities are terrifying. People don't start businesses when there is no possibility of economic growth, and they stop spending money on anything besides bare essentials. In such a scenario, I could see economies swinging back and forth between stagnation and depression, with no prospects for growth. With a growing population, you can probably imagine how this becomes increasingly problematic over time.
I don't know what the ideal solution is on the Keynesian vs. Austrian spectrum, but I don't believe we will go back to fixed commodity standards that facilitate deflation. If we do, the next Great Depression will surely convince people the erosion of stability is not worth it.
In that sense, BTC primarily is and will always be seen as a tool for personal enrichment, not so much as a form of currency, and definitely not as a global reserve currency itself. It will just provide people who have already amassed wealth a way to hedge it. It's like gold in a vault, not spending money. Of course, this doesn't solve the actual problem of economic stability and reserve currencies.
