And El Salvador is already moving away from Bitcoin and into products that actually work. That didn't take "decades", it's happening right now. And the same goes for thousands of other companies and countries who are trying to solve actual consumer demand and not just meme speculation.
Bitcoin's days are numbered, and in the world of technology, it's not going to be "slow".
Just FYI, L2 Bitcoin such as Liquid and Lightning work beautifully in El Salvador as exchange currencies. There is room for improvement (specifically auto-return addresses coded in to a transaction) but they would seem rather trivial to solve.
Right now the intermediary (e.g., Chivo who supply support to sellers) can and almost certainly does end up with all the money when there is a failure, and failures are not uncommon. If there were a will on the part of the government and/or a desire on the part of sellers, this problem should be able to be solved readily.
A new more highly controlled shit-coin would offer nothing toward a solution. That is exactly what the existing central bank powers are trying to roll out with their CBDC's and they are trying to normalize and implant it via fud and spam by 'social media influencers' on all available channels. These people could 'catch the train' at great expense, but it would be cheaper if they could pull of any one of the numerous shit-coin scams they are trying to peddle.
Thankfully Keiser still has some sway in the El Salvador govt so it seems, and he is very awake to the scam. And never shy to speak up.
