Something worth noting is that for all the sanctions being announced they're not really going after Putin's wealth or that of his cronies. These are hundreds of billions of dollars, stolen from the Russian economy, that are used to buy real estate in Western countriees, luxuries and used as political contributions. This would be what would really put the squeeze on Putin but because it also threatens business interests in the west, they're opting instead for sanctions that will make life harder for Russian people.
