No, that fact means that other countries will accept Bitcoin because they have been looking at El Salvador and this country is doing well. There are also some other countries that successfully implement Bitcoin as payment means. To prove you wrong, I want to give you an example of Louisiana state government. This state in the USA accepts Bitcoin payments.
El Salvador is a first nation makes Bitcoin Legal Tender and practically they have been doing it seriously since June 9th 2021.
El Salvador's law: a meaningful test for Bitcoin is a report from PwC.
There is another country make it after El Salvador, Central Africa Republic about one year later but 3 years after El Salvador, they are the only nation follows this law of Bitcoin Legal Tender at national scale.

Simply put - they don't see as many possibilities as those listed in your post. These countries would use every opportunity presented to them in order to make their situation more stable and better. Others would like to regulate crypto to the brim, in general.
