I don't think blockchains are particularly well suited for solving El Salvador's actual problems, like gang violence.

There's a not entirely implausible theory that says Bukele is going for Bitcoin specifically because El Salvador uses the US dollar and is thus prevented from taking the typical path of printing more its own currency to "solve" problems. With Tether and various dodgy custom apps in the mix, they can now print money.
