I understand the intention, however, the majority of those broad-stroke sanctions hurt the most progressive and self-reliant citizens first, the current regime support is extremely low for those people already. Putin's main support base will start to feel anything only in a few weeks, when the economy crashes and inflation starts reflecting on the base needs. Most of the "deep nation" have only internal passports (never travel abroad), work in a government-funded spheres of economy, use mostly state-sponsored sources of information. Sanctions will probably just reinforce the narrative of "the ruthless enemies are encircling the motherland and can't wait to rip it apart".
