The problem is that most of the people in crypto see Bitcoin as an asset like a stock to invest in and then sell later. No one even thinking about the future of Bitcoin as means of currency.
In my opinion, it's a bit of an exaggeration to say that no one. because not everyone thinks so. In fact, it is possible that there are actually many people who want to use or apply Bitcoin as a means of payment but are constrained by several things. One of them is the prohibition from the government to use Bitcoin as a means of payment. so, not because of everyone's unwillingness. but on the other hand, aren't there actually more and more payments with Bitcoin? And more and more people are aware of Bitcoin and accept Bitcoin as payment in countries where it is legal?
Maybe it's more a matter of time, how the world responds to the use of Bitcoin for global payments more easily.
