I like your hot take and I partially agree. As long as Bitcoin is in the process of filling its predestined place (pick your number, is it to replace all gold, all bonds, etc) people are unwilling to spend it.
However, I think at the same time we should not get complacent about the status quo because eventually, we all want and need Bitcoin to become the global currency.
Also, if I am not mistaken, in El Salvador the main reason why merchants are not taking Bitcoin is volatility but I might be mistaken. And in any case, I agree with you that Gresham’s law plays a big role in Bitcoin adoption.
