Yes. We die but the consequences of our actions resonate indefinitely. Ideas make good idols and people do not. Better Родина-мать зовёт! (a statue in Stalingrad approximately "Motherland [ie Russia] calls") and Liberty, which are both definitely statues about ideas than the Lincoln Memorial for example, or even arguably the "Statue of Unity" which is named for Unity but in practice is explicitly a statue of a specific man - Sardar Patel.
