Military operations would do that as well. Ukraine is destroying Russia's oil and gas industry right now. Sanctions or not, that oil and gas is becoming unavailable. Either way, preventing innocent Ukrainians being slaughtered with your money will do harm to your economy; continuing to get cheap oil from Russia inevitably pays for evil.

Might as well do whatever is most effective, which is likely to be harsh sanctions followed by military action to fully enforce them.
