Well the post could really make sense and has a point, but maybe people are being blinded with features of bitcoin that they didn't found on fiat. One of those features could be the decentralization of bitcoin, making tyhe assets of users be free from the manipulation of the government which people or investors highly prefer for they want complete power over their assets, who wouldn't want to, right? Plus the convenience. So no matter how sensible the concern said above, if people don't wanna believe you, they won't.
