I agree with everything that you outline here.. except I do not agree with any assertion that this kind of an adoption/initiative of bitcoin could be reasonably (or informatively) characterized as having had "failed" in any sense of the word with less than 1 year of having had gone into effect.. remember the actual law went into effect on September 7, 2021..
Furthermore, you indicated that the law gives citizens and residence of El Salvador more options.. whether they are actually in the country or transacting from outside of the country... If you, or any other member, wants to proclaim some kind of "failure" then you better come up with some data to support it, and I am not even saying that any of us need to agree with your data, but merely proclaiming that "failure" exists needs some kind of quantification and/or support for what is meant by that.. Sure it is possible to come up with various examples, such as 1) the chivo wallet had problems or 2) El Salvador is no longer offering a bitcoin bond, or 3) Only 10% or less (I am not sure about the number) of remittances have converted over to bitcoin from Western Union, or 4) on paper El Salvador is in the negative in terms of how much it spent on BTC versus how much the BTC are currently worth on the spot market, and/or 5) other examples of supposed failure or less than stellar success.. blah blah blah.. yet just coming up with a list of examples of less than stellar success is likely not going to be very convincing if there are not attempts to show various ways that adoption and awareness of bitcoin is increasing in the country (even if it is going at a rate that might well be slower than expected).
Ever since El Salvador announced that they had legalized bitcoin as a legal tender as well as a currency, I remember that I haven't once spoken about the failure of that adoption. I didn't imagine that it actually failed even though it was a failure talked about by several people on the forums. So if you say I said El Salvador is failing about its bitcoin adoption then I don't agree either. So I'm on the same side as you who might disagree if people assume that the adoption of bitcoin in El Salvador has failed to meet its goals.
At this stage I understand that El Salvador is not perfect in terms of careful preparation of bitcoin adoption plans. They were the first to state in law that bitcoin is legal as a currency and means of payment, their drawbacks are talked about but we cannot expect them to be perfect from the start. In contrast to later countries that also want to legalize and adopt bitcoin, they learn from El Salvador's imperfections so it may be slightly more likely to achieve a success percentage over El Salvador.
For sure, I wanted to clarify since you did use the word failure, and even if you had been referring to how others seem to see the El Salvador adoption matter, the word failure was still used, so it seems good for us to clarify the matter and to go over what might constitute failure for anyone who might want to present the El Salvador adoption matter as a failure.
There are forum threads on the topic and surely a decent number of naysayers in regards to El Salvador's bitcoin adoption - and surely it seems way too soon (premature) for them to have enough evidence to establish such a status even though some members do seem to either enjoy making those kinds of characterizations or citing lame mainstream articles that are making similar assertions about El Salvador's purported bitcoin adoption failure.
On a personal level, I do not mind allowing the facts take us where ever they might take us, so surely there should not be any problem attempting to either figure out various facts on the ground regarding what is happening in El Salvador and also to attempt to figure out if there might be either positive or negative developments in regards to how El Salvador's bitcoin adoption might be playing out.
