I'll make a case for Javier, not "the politician Javier" and certainly not the "bitcoiner Javier". I don't believe any change will come out of voting, so I don't do it. That being said:
I'm from Argentina, I've always lived here.
The first time I hear about Milei it was trough a frind, one of those friends that you know they don't know much about politics or economy but that sparked my curiosity in the austrian school of economics and Atlas shrugged wich was the first step in what ended up being my journey down the Bitcoin rabbithole.
Javier Milei, since 2016, started to appear on TV making a case for closing the central bank, full libertarian, recommending one book after another. His charm and hilarious bursts of angry against some statist clown has proven to be an amazing tool to expose an enormous amount of people to libertarian ideas and that is what he called "the cultural battle".
Bitcoin and Milei: Javier has talked about Bitcoin in the past, I think before even he started his career in politics, and as far as I can tell he was consistent in his view as a tool against central banking.
No one in his or her right mind will argue that he is a bitcoin hero, and I don't know why some people portraits him like that besides the casual mentioning of Bitcoin here and there.

A bit of perspective

What I find valuable in this is that today, a big chunk of young people supports him, who knows how valuable that is in forming future generations of freedom loving people. For those who are not from here I can't even start to explain how far was the oberton window regarding economics and now we have a guy (with a crazy hair lol) that talks about making the streets private, talks about secession and even literally talks about demolishing the central bank.
I know that I ended up knowing about bitcoin thanks to him indirectly though, but still. I agree with you that you should kill your idols at some point, also the shitcoin stuff with CoinX, I agree with that, but what I don't understand is how can you not have at least some perspective in the positive side of this.
Even me as someone who advocates to not trust any politician and don't vote can appreciate that whatever he is doing is pushing forward the freedom ideas, who knows what impact that can have. I find this interesting to see, at least from people here and even for people outside Argentina.
